Wallpapers are images used on a computer screen as the desktop background.

Small images are not suitable as wallpapers as they are typically taken at low resolutions. These small images can be tiled across the desktop but this doesn’t produce the best result.

1. Click Start, and then click Control Panel.
2. Click Appearance and Themes.
3. Under Pick a task, click Change the desktop background.
4. On the Desktop tab, do one or more of the following:

• In the Color box, select a color.

• In the Background list, click a background picture. In the Position list, click Center, Tile, or Stretch to define how your picture will be displayed.

• Click Browse to search for a background picture in other folders or on other drives. You can use files with the following extensions: .bmp, .gif, .jpg, .dib, .png, or .htm. In the Position list, click Center, Tile, or Stretch to define how your picture will be displayed, and then click OK or Apply.

• If you want to use a picture from a Web site, on the site, right-click the image, and then click Set as Desktop Background.

• To see a colored background you must select none from the Background drop-down menu. Also, if you choose an .htm document as your background picture, the Position options are unavailable; instead, the .htm document automatically stretches to fill the entire background.
