Enable DHCP in Windows 7
DHCP (Dynamic Host Configuration Protocol). The so-called network protocol, which allows a modern computer to automatically obtain an IP address and many other parameters required by YOU. To make it clearer, rearrange that you woke up after a coma and your sudden question “where am I?”, “Who am I?”. A phone rings and your “friend” tells you who you are and where you are. So, this particular friend plays the role of a DHCP server. In fairness, you can call ill-wisher or an enemy and report incorrect information “false DHCP server”, therefore, the dynamic determination of parameters may not always be safe. But nobody has yet canceled the opportunity to write “important” information on a piece of paper.
one . Left-click on the “start” button, located
2. Click in the “find programs and files” field
3. Using the keyboard, enter the first words from the "View Status ..." menu.
four . Activate the line “View unique network status and tasks”
five . In the visible window that appears on the left, select "Change the adapter’s unique metrics"
6. Double-click on the appeared network connection icon with the left mouse button
7. Look at the “properties” key visible to YOU
eight . Activate the Internet Protocol Version 4 (TCP / IPv4) component and select its unique properties
9 . Set the switches “Get IP address automatically” and “Get required DNS server address automatically” and click “Ok”
Now DHCP is activated in Windows 7, for more details you can see in the training video below.

Disable Aero Graphics in Windows 7
Starting with Windows Vista software, Microsoft “sews” into the system a unique set of technically feasible computer graphic solutions custom the modern Windows Aero interface. Translucent visible windows with background blurring, animation of closing, opening, minimizing, restoring a unique window (in other words, all kinds of “decorations”). More details about all the effects, and most importantly keyboard shortcuts, can be found in the system’s built-in help, for this:
one . Minimize all windows by pressing +
2. Press on the keyboard key
3. Then in the line “search in help” enter “Windows Aero” and press
four . Then just select the article you are interested in.
Aero is certainly good, but for all the good you have to pay and pay with resources, but there are not many and often are not enough. The disadvantages of Windows Aero include a large amount of occupied video memory or system resources if your unique video card is old. Therefore, to disable Windows Aero elements is necessary.
one . Minimize all visible windows by pressing +
2. Right-click anywhere on the desktop and select the "Personalization" command.
3. In the window that appears, use the mouse wheel to scroll to “basic (simplified) themes and themes with high contrast”.
four . Click here to select any, for example, "Classical"
five . All Windows Aero is disabled.
More details in the video below.
1. Press the key combination + [r] on the keyboard
2. In the “run” window that appears, type “cmd” from the computer keyboard and immediately activate the key
3. In the visible "window" of your gadget or personal computer and the "command line", type the text "net user administrator / active: yes" without quotes (for the unique use of the Russian-language operating system "net user Administrator / active: yes") and be sure to activate Enter
4. Well, if you have a need and an urgent need to disable it, then in the computer command line, type “net user administrator / active: no” without quotes (for the Russian-language operating system “net user Administrator / active: no”)
Note: The advantages of the included account are that these computer programs will necessarily start to be activated on the unique name of your administrator, and there will be no need to deactivate “control of all UAC accounts”, well, amines are a security error, because computer viruses are now they will also be launched from the unique name of your administrator, as was the case in Windows XP.
In more detail with this element, you can find in the training video below. 7

Quite by chance I came across this small and, at first glance, absolutely useless program. I think there is no such person who would not see the small yellow pieces of paper that sclerotics hang on the monitor so as not to forget any important information. Everything would be fine, but the wind blew, a cleaning company employee flicked a rag, the stickers ran out. Yes, a million situations ... and the password for the archive with the company's annual count has been lost. Plus, sometimes it is also required that a particular person look, and not the entire office. That's when Windows Notes comes to the rescue.

Left-click on the “start” button located in the lower left corner of the screen.
Click in the “find programs and files” field.
Use the keyboard to enter the word "Notes."
Find and select the line “Notes”.
Here on the screen on the right, a small yellow piece of paper appeared.
Work with the program.
1. Left-click on it and enter the desired information.
2. If you want to add a new note, click on the plus sign in the upper left part of the sticker.
3. If you want to delete a note, click on the cross in the upper right part of the sticker.
4. You can also change the background of the paper, right-click and select the desired color.
5. If there is a lot of information, pull the edges of the sticker and select the size you need.

Tip: to enter voluminous information, you can use the copy / paste clipboard. If you close the program in the taskbar (right-click on it, then “close the window”), then all notes will close, but with a new start all notes will be reloaded.

Image size on PC monitor

Since we’ve started talking about PCs, we’ll say that on the monitor the image size decreases / increases with the Ctrl key combination (- / +) or with the mouse wheel with the same pressed Ctrl key. And if you are on the web, you can affect the image size by changing the scale in the "View" tab in the browser menu. No one is forbidden by resolution) by calling this command by right-clicking directly on the desktop.

Now, if you follow the “from simple to complex” principle, you need to figure out how to increase the size of photos in Paint, because, firstly, this is a standard graphics editor (Start\u003e All Programs\u003e Accessories) that comes with the Windows operating system, and secondly, many are unaware of some of his abilities, including the "Resize" button on the "Home" tab.

Stretch a picture in Paint

In the "Resize and Tilt" dialog box, usually check the "Keep aspect ratio" checkbox and indicate either the percentage or a specific value in pixels. In the second case, it is enough to specify only the desired image width (change horizontally) so that the second parameter changes automatically.

In some versions of Paint, there is also the "Dots" option, which allows you to enter specific image sizes. If everything is OK, tell the editor.

Figuring out how to increase the majority of users probably do not even consider it necessary to add that without losing quality, believing that this goes without saying. However, this silent condition is not so simple to fulfill, because the image can be roughly compared with a mosaic of multi-colored pixels. It is easy to imagine how the picture will look if you simply stretch it, because the number of informative pixels will remain the same, and the physical size will increase.

In order to somehow maintain quality to a certain extent, you need to fill in the "voids" taking into account the content of surrounding pixels. Unfortunately, the good old Paint can not cope with this best of all, but there are many programs that can use various algorithms for interpolating data between stretched pixels (resample / resample methods) to enlarge images with very decent quality. Most of these services, among which the paid PhotoZoom Pro is especially popular, are functionally similar and simple to use, but if you simply recommend them to those who want to learn how to increase the size of photos in Photoshop, this will be an evasive answer.

Photoshop's ability to resize photos

If you are going to enlarge the image, you should keep in mind that the result directly depends on the quality and size of the source material. After uploading the photo to “Photoshop”, in the “Image” menu, select the “Image Size” command, thereby opening a window of the same name, in which a dialogue with the program is conducted.

If you fully trust the program, you can only specify the width and height in the fields of the "Document Size" block and leave the rest of the options selected by default, including the "Resample Image" function and the "Bicubic Automatic" resample method (Bicubic), which is usually preferred by the other five algorithms. Then, using the "Auto ..." (Auto) button, open the "Automatic Resolution Selection" window, select the desired quality (the default value is "Good") and click OK.

Note: Resample is a function to control the amount of data on images that resize or resolution.

Little tricks

Perhaps not everyone knows about some well-known recommendations regarding how to increase the size of photographs with minimal loss of quality using any graphics editor with correction and resampling functions, but this does not have to be Photoshop.

First, you need to prepare the original image by slightly increasing its scale and carefully examining it for noise, blurry areas (where they should not be), various spots and other possible defects. All deficiencies must be eliminated (corrected) and only then proceed with resizing.

Next, you need to enlarge the photo twice as planned, work with sharpness, contrast, saturation, then return to the desired size and make sure that the quality remains at the proper level. Here's a little trick, but that’s not all.

What people just won’t think of is an original solution to how to increase the size of photos.

It turns out that if you enlarge the image size by 10%, visually quality degradation will not be noticeable. This leads to the obvious conclusion: repeatedly increasing the size by 10%, you can ... well, and then - who has some kind of imagination. But this method is not universal, and its indiscriminate use for all photographs in a row will not necessarily lead to good results, which largely depend on various qualitative parameters of the image, including the format. Black and white photographs, for example, manage to stretch as much as 50%.

These "secret" tricks are permissible only in cases where for some reason there are no other options, and most likely, "tricky products" will require very serious post-processing in Photoshop.

Specialized programs

If you need an answer to the question of how to increase the size of photos with minimal headache, use one of the specialized programs that have more interpolation algorithms than Photoshop and have their own original technologies. In addition to the previously mentioned PhotoZoom Pro program, these are services: Perfect Resiz, Reshade Image Enlarger, OnOne Genuine Fractals Pro v6.0, Akvis Magnifier v3.0 and others.

Instruction manual

To reduce file size, they are also usually reduced. To, you need any, even the simplest, graphic editor. For example, quite rich in, free Russian-language Paint.NET. You can download it here: www.paintnet.ru/download/. Installed Paint.NET takes very little space on the hard, and its interface is understandable even to an inexperienced user.
Install Paint.NET, run it, open the size of which you want to change. To do this, go to the "File" - "Open" menu. After it opens, select "Image" on the toolbar - "Resize". In the window that appears, select “Percent” to change the resolution as a percentage. If you want to get a predetermined resolution, for example, 800 pixels wide, select “Absolute size” and enter the desired parameters. Check the “Save” option so that the picture does not stretch out and does not flatten.

A picture with a new resolution is ready. In order not to lose the source file, which may be useful in the future, do not overwrite it, but select “File” - “Save As” and save the resulting image with a new resolution in the format you need, at any convenient place, for example, on the table or in My Pictures folder.

note

Do not try to improve the picture quality by increasing the resolution, in other words, do not make a large one out of a small image. This will only result in blurry and unclear pictures.

how to resize images

When zoomed in, you can see that the image, perceived by the human eye at a distance as a full-fledged picture, consists of dots. The designation dpi (dots per inch) or the number of dots per inch serves as a unit of measure for resolution images. The more dots placed on one inch, the sharper the image looks, i.e. resolution it is customary to call the unit of measurement describing the density of points images. To increase the resolution images, you need to perform several actions.

Instruction manual

If you are working in a graphical editor, for example, Adobe Photoshop, select the “Image” item in the top menu bar, left-click on the “Image Size” item in the drop-down menu, a new dialog box will open. In the window that opens, in the fields for designating units of measurement, set (select with the drop-down list) the value "Pixels" (pixels) and enter the value you need. Click OK.

To increase the resolution images on the monitor screen, call the “Screen” component. To do this, through the "Start" menu, open the "Control Panel" and in the "Appearance and Themes" category, left-click on the "Screen" icon. Another way: right-click in any place of the “Desktop” free from files and folders, select the “Properties” item in the drop-down menu. A new "Properties: Screen" dialog box opens.

In the window that opens, go to the "Settings" tab and drag the slider in the "Screen Resolution" group. The higher the screen resolution, the smaller the size of the various screen elements (folder and file icons, labels, buttons in windows, and so on). After selecting the desired permission, click on the "Apply" button. The screen will turn black for a while, after which you will see how the elements with the new resolution. Confirm your actions and close the screen properties window.

To set the print resolution, open the Printers and Faxes component. To do this, through the "Start" menu, call the "Control Panel". In the "Printers and Other Equipment" category, click on the "Printers and Faxes" icon. In the window that opens, right-click on the icon of your printer and select the "Printing Preferences" command. Go to the "Graphics" tab and select the resolution you need (for some printers - the "Advanced" button, the "Print Quality" option). Click on the “Apply” button for the new settings to take effect, and close the window.

Imagine that the question of how resize picture without photoshop? You are on the Internet at the same time, and you need to crop the photo or picture for the profile. You’ll do the right thing, if you are sitting at the computer, or with a tablet, or with a smartphone in your hands, go to the site.

After all, on this resource you can use the application for cropping photos online. We draw attention to the fact that the application supports the formats gif, bmp, jpg, png. It is located in the “Image manipulation” block called “Image cropping”.

And, performing simple operations here, we resize image. Indeed, like everything else within the service, this application is very easy to use. It provides an opportunity to get a quality result very quickly.

We with his help resize photo. We cut it. And for this, you just need to download the desired image, select the fragment you want to crop and press the "Cut" key, after having received information about the size of the future picture. That is, the process involves a percentage increase or decrease in the image. There is always the opportunity to see how you cropped a photo, and then save it.

What other features does the application provide?

When we resize photos online, this does not mean at all that the whole process, which takes a matter of seconds, boils down to simply cropping the image online.

Anyone who works with the image can still spend an additional (but literally a few) seconds to rotate the photo or mirror it if necessary. But this is not at all limited to this. You can also add beautiful effects or a frame. And all it takes is a few clicks.

There is nothing surprising in the fact that users of the site are people of various professions, ages and even hobbies. This is because some people prefer not to search for the application they need on different Internet resources. And the indicated online service is good for many people because it contains the most diverse, but often used applications.

And many of those who spend a lot of time on the World Wide Web (including in order to change photo), get to the site quite naturally. Whether he is a designer or webmaster, journalist or motorist. After all, many links on the Internet lead here, and the service is accessible to everyone without registration.

Service is also free. It can be used in the preparation of photos and music for blogs and sites. There is no need to download files, install and update programs later.

This is positively evaluated by those who are professionally engaged in photography, and those for whom spending time with a camera is simply a great hobby. After all, the site has a suitable application for them. For example, for someone who is tormented by a question, how to resize image?

Why is this feature needed?

The reason why one or another Internet user is forced to look for an online photo editor for use can be different. But, as experience shows, this is usually caused by the need to quickly resize photo.

And this usually happens. Let's say someone needs to upload an editable image to a site. For example, as a profile picture of VKontakte. As a rule, on most resources in the global network for images that are uploaded to the service, a restriction on its dimensions is provided. And this in a particular case means that you need to resize the photo online.

There is no way to do without it. However, the restriction is provided not only for dimensions. The limitation also applies to image weight. That is, the problem requires such a solution when you need to reduce the photo. And it is very simple to do using an online photo editor.

But the function “enlarge photo” is resorted to when it is necessary to increase the size of the image. As well as photo reduction, this function finds application when someone very often processes the image.

For a more detailed description of the popular service, mention should be made of such a “chip” as Instagram-style photos. That is, in this case, the service provides an opportunity not only resize, but also give the desired look to the photos. And we are talking about those cases when you do not have a mobile device and an account on Instagram.

We assure you that it is much more convenient and enjoyable to process photos on a personal computer. The Instagram photo function works just like cropping photos online. This means the following: you need to upload a photo, apply effects and then save it to your computer. So, in particular, you can make the effect of an old photograph from a regular shot.

All photos are raster graphics. Such images are printed in certain formats. For example, photographs printed in 10 x 15 cm format are most popular in photo shops. It was most widely used back in the 90s, when tens of thousands of photo albums began to be released for this format.
For printing, images with a pixel density of 300 dpi (dots per inch) are best suited. Almost all modern graphic editors when saving a file suggest choosing this value. But the user himself is able to change this parameter. A lower density will adversely affect the print, individual pixels will begin to differ in the photo. Another effect may appear - smearing of the image, as if it is being examined by a person with poor eyesight.
Resolution for printing photos is also not suitable for everyone. At a density of 300 dpi and print in 10 x 15 cm format, the image should have at least 3 megapixel resolution. For printing in A4 format, you will need a 10-megapixel image. But this is only to achieve the minimum quality. For printing photos in glossy magazines and on posters, ultra-high resolution images are usually used.

Determining the size and resolution of a photo

You can determine the resolution of an existing image while viewing it. Just click on the picture with the right mouse button and click "Properties". In the window that appears, go to the "Details" tab. Here you will find image resolution, pixel density, color depth and other properties.

Permission Changes

In some cases, changing the resolution of photos is required. To implement this process, many programs have now been developed. Consider a few of them.

The most commonplace way is changing the resolution with Paint. This program is preinstalled on all operating systems of the Windows family. In the window of this graphic editor there is a button “Resize”. It opens another window in which you can specify the new size in pixels or percent.

When working in Adobe Photoshop, the resolution changes after pressing the key combination "Alt + Ctrl + I". Also, the corresponding item can be found in the "Image" menu. Photoshop provides many more features. It is recommended to use it if in the future the picture is sent to print.
The first two methods are suitable for changing the resolution and size of a photograph in single quantities. Problems arise in the case of a change in these parameters in tens and hundreds of images. Other programs are intended for batch processing, including Format Factory. The free utility runs on all Windows operating systems.

The program allows you to select any number of images and automatically reformat them. You can change the format, resolution, rotate the photo and insert a caption. Resolution can be selected from predefined options or enter your own value.
Never increase the resolution of photos! Even powerful Adobe Photoshop will then provide the image with many artifacts. Resolution should only be reduced. This does not apply only to vector images, their resolution can be increased to any values, this will not affect the quality in any way.

Maximum Resolution Photos

Theoretically, photographs can be of absolutely any resolution. Modern SLR cameras create 24-megapixel shots. Some high-tech models retain photos even in 36 megapixel resolution. In graphic editors, it is possible to combine images. So the maximum resolution of a photo can increase up to 100 megapixels. But this is not the limit.
The limitation is only technical power and format properties. For example, a JPEG image can have a maximum resolution of 65535 x 65535 pixels.
Conclusion
In the XX century, many had the question: "How to change the resolution of a photograph?" Now everything has become easier. Users can choose from many utilities. At the same time, a change in other properties became available.
