The X Window System was one of the earliest systems to include support for an arbitrary image as wallpaper via the xsetroot program, which at least as early as the X10R3 release in 1985 could tile the screen with any solid color or any binary-image X BitMap fileIn 1989, a free software program called xgifroot was released that allowed an arbitrary color GIF image to be used as wallpaper and in the same year the free xloadimage program was released which could display a variety of image formats (including color images in Sun Rasterfile format) as the desktop background Subsequently a number of programs were released that added wallpaper support for additional image formats and other features, such as the xpmroot program (released in 1993 as part of fvwm) and the xv software (released in 1994).

The original Macintosh operating system only allowed a selection of 8×8-pixel binary-image tiled patterns; the ability to use small color patterns was added in System 5 in 1987 MacOS 8 in 1997 was the first Macintosh version to include built-in support for using arbitrary images as desktop pictures, rather than small repeating patterns

Windows 3.0 in 1990 was the first version of Microsoft Windows to come with support for wallpaper customization, and used the term "wallpaper" for this feature. Although Windows 3.0 only came with 7 small patterns (2 black-and-white and 5 16-color), the user could supply other images in the BMP file format with up to 8-bit color (although the system was theoretically capable of handling 24-bit color images, it did so by dithering them to an 8-bit palette).\ In the same year, third-party freeware was available for the Macintosh and OS/2 to provide similar wallpaper features otherwise lacking in those systems. A wallpaper feature was added in a beta release of OS/2 2.0 in 199

Robert R. Wiggins, "All systems go. (Software Review) (System Tools 5.0 with MultiFinder.)", MacUser (1 March 1988). Many of the cdev modules that come with System Tools 5.0 are for the Macintosh II, including a new one called "Color" that allows you to change the highlight color, the color used as a background when text or an icon is selected. The General cdev also adds the ability to set the desktop pattern color on a Macintosh II.

A new control panel lets you display your favorite picture on the desktop, with options to scale, center, or tile the image (see the label "Desktop Pictures" on the combination screen shot). And if you'd prefer to stick with desktop patterns, Mac OS 8 provides 40 to choose from.

There are so many customizable options, though, it's hard not to love the program. Even the background screen (which Microsoft calls "wallpaper") can be changed to display a custom design, so you can have your company logo on the opening screen with a .PCX file and a 5-minute change to the default settings.

Jump up ^ Charles Petzold, "Working with 24-bit color bitmaps for Windows," PC Magazine (10 September 1991). Every user gets seven device-independent bitmap (DIB) files with the retail package of Microsoft Windows. You can use these DIBs as wallpaper to decorate the Windows desktop. Five of the seven bitmaps have 4 bits per pixel to represent the 16 standard VGA colors. The other two are monochrome bitmaps that use 1 bit per pixel. Enterprising Windows users who frequent CompuServe can dig up some 8-bit (256-color) DIBs from the data libraries. Generally, these have been converted from existing files that were in the Compu-Serve Graphics Interchange Format (GIF). These 256-color DIBs are usable as wall-paper on the IBM 8514/A adapter and on those Super VGA boards that support 256 colors under Windows. Windows will use the colors in the DIB color table to set a palette for the wallpaper display. If you think about it, though, the poor performance is entirely understandable. Windows or more precisely, the device driver for the video adapter must convert each 24-bit pixel into an 8-bit pixel-bit value that's an index into the system palette.

Jump up ^ Roger Gilbert, "33 unsung shareware programs", MacUser (1 October 1990). Are you envious of a colorful background picture on someone else's desktop? Start using ColorDesk, an advanced version of the INITs that allow illustrations to replace the background patterns. ColorDesk is a cdev that allows a color PICT image to serve as a background scene and lets users change the image at any time with a new picture located in any folder on a hard disk.

In OS/2 and now Windows 3.0, where memory limitations are not as critical, animated screen savers are beginning to appear. For example, John Ridges's public-domain program for the OS/2 Presentation Manager, Deskpic, combines a screen saver with a desktop picture program.
