How to Resize and Crop a Photo in Windows 7's New Paint Application
Windows Paint, Windows 7's improved drawing program, lets you resize or crop photos. Resizing photos makes them small enough for e-mails or size-specific for inclusion in a document. Many photos can also be improved by cropping — cutting out distracting elements and keeping just part of the photo — to concentrate on the most important part of the photo.
In the Pictures library, click a photo to select it. Click the triangle next to Preview and choose Paint from the menu.
Alternatively, you can open Paint from the Windows Photo Viewer. Choose Open→Paint to open the photo you’re previewing.
Click the File menu button to the left of Home and choose Save As.
The Save As dialog box opens. You can ignore the menu of file types, unless you know you want a particular file type.
Change the name in the File Name field to create a new copy of this picture. Click Save.
You’re now editing the new copy, so the original, unaltered file still exists under the original name. You may not need to do this for every photo, but saving a copy gives you some insurance against edits you can't fix.
To shrink the image, click Resize in the Image panel.
The Resize and Skew Dialog box appears.
In the Resize and Skew dialog box, enter a percentage less than 100 (without the percent sign) in the Horizontal field. Click OK.
If you're not happy with a change, you can undo each step by clicking the Undo button above the Home tab (or by pressing Ctrl+Z).
To crop, click Select in the Image panel above the photo. In the photo, click and drag a box over the area you want to keep and click Crop.
Everything outside this box will be deleted.
Click the Save button.
The newly cropped image is saved. However, if you decide you like the other one better, you can always go back to the original version of the image.
