Desktop Wallpapers

The terms "wallpaper" and "desktop picture" refer to an image used as a background on a computer screen, usually on the desktop of a graphical user interface. 'Wallpaper' is the term used in Microsoft Windows, while the Mac OS avoid mixing terms by calling it a 'desktop picture'. Earlier, the term "desktop pattern" was used to refer to a small pattern, that was repeated to fill a screen.
Images used as computer wallpaper are usually a data file or structure representing a rectangular grid of pixels. They are points of color on a computer monitor, paper, or other display device, with the same size as the display resolution in order to fill the whole background. Users with widescreen monitors have different requirements, although images designed for standard monitors can often be scaled up or cropped to the correct shape without loss of quality.
