Download Wall paper coverings for walls have been around a long time, almost as long as mankind has had access to paper. The first use of wallpaper was probably in early China (about 2000 B.C.). But its method of attachment was temporary and crude. About 105 A.D. rag paper was invented and a product was churned out that was similar to the paper we use today1.

Download Wall Paper making spread from Asia, through the Middle East to reach Europe in about the 1100s. In 1481 Louis XI, King of France, had portable wallpaper made, so that he could take the decorations with him as he traveled from castle to castle. Most wallpaper was probably pasted on walls at those times, as both decoration and an easy way to chink up cracks that let in cold air in winter. Yet, wallpaper as we know it (with repetitive patterns) had to wait for the printing press.

Free Computer Wallpaper the terms wallpaper and desktop picture refer to an image used as a background on a computer screen, usually for the desktop of a graphical user interface. 'Wallpaper' is the term used in Microsoft Windows, while the Mac OS calls it a 'desktop picture' (prior to Mac OS X, the term desktop pattern was used to refer to a small pattern that was repeated to fill the screen).

Images used as computer wallpaper are usually raster graphics with the same size as the display resolution (for example 1024×768 pixels, or 1280×1024 pixels) in order to fill the whole background. Many screen resolutions are proportional, so an image scaled to fit in a different-sized screen will often be the correct shape, albeit that scaling may impact quality. PNG and JPEG format are common.

Users with widescreen (16:9 or 16:10) monitors have different aspect ratio requirements for wallpaper, although images designed for standard (4:3) monitors can often be scaled or cropped to the correct shape without loss of quality.

Wallpapers are sometimes available in double-width versions (e.g. 2560×1024) for displaying on multi-monitor computers, where the image appears to fill two monitors.

Some display systems allow unconventionally-proportioned images (1:1, 2:1, or even 1:3) to be scaled without change of proportion, to fit the screen, whether it be 16:9 or 4:3. The image would be sized just large enough that one pair of edges touch the edges of the screen, but not all four, as this would unduly distort the image.

Most display systems are capable of specifying a single-colour to use as the background in place of a wallpaper, and some (such as KDE or GNOME) allow colour-gradients to be specified. Microsoft Windows 3.x and 9x systems allow using editable repeating two-color 8×8 tiles for background.

Some desktop systems, such as Mac OS (version 8.6 or later), KDE (version 3.4 or later), and GNOME, support vector wallpapers (PICT in Mac and SVG in KDE and GNOME). This has the advantage that a single file may be used for screens of any size, or stretched across several screens, without loss of quality.2012 Wallpapers For Desktop Here’s another great roundup of desktop wallpaper calendars for February 2012.
