Wallpaper (also desktop picture and desktop background) is an image used as a background of a graphical user interface on a computer screen or mobile communications device. On a computer it is usually for the desktop, while for a mobile phone it is usually the background for the 'home' or 'idle' screen. Though most devices comes with a default picture, users can usually change it to files of their choosing.
"Wallpaper" is the term used in Microsoft Windows before Windows Vista (where it is called the Desktop "Background"), while Mac OS X calls it a "desktop picture" (previously, the term desktop pattern was used to refer to a small pattern that was repeated to fill the screen).

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 file. In 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 1991.
A 'live wallpaper' is a type of application that works on a mobile device using the Android operating system. The application works as a wallpaper – providing the background image for the home screen—but also works as a conventional application since it can provide user-interaction with the touch screen (allowing the image to change dynamically, for example) and access other hardware and software features within the device (accelerometer, GPS, network access, etc.).
Similar functionality could be found in the Active Desktop feature of Windows 98 and later versions. There is also third party software that provides this feature for various operating systems.Dynamic backgrounds
In Mac OS X
Mac OS X has built-in support, via the Desktop & Screen Saver panel in its System Preferences, for cycling through a folder collection of images on a timed interval or when logging in or waking from sleep.
Additionally, OS X has the native ability to run a screen saver on the desktop; in this configuration, the screen saver appears beneath the desktop icons in place of the system wallpaper. However, OS X does not come with a built-in interface to do this; it must be done through Terminal commands or various third-party applications.

Free Wallpaper For Computer Biography
The Early Middle Ages (AD 400 to 1450) saw a decline in awareness of classical culture in Europe. During this time, the only repositories of knowledge and records of early history in Europe were those of the Roman Catholic Church. Hermits, monks and priests used this historic period to write the first modern biographies. Their subjects were usually restricted to church fathers, martyrs, popes and saints. Their works were meant to be inspirational to people, vehicles for conversion to Christianity (see Hagiography). One significant secular example of biography from this period is the life of Charlemagne by his courtier Einhard.
Meanwhile in the medieval Islamic civilization (c. AD 750 to 1258), biographies began to be produced on a large scale with the advent of paper, beginning with the Prophetic biography tradition. This led to the introduction of a new literary genre: the biographical dictionary. The first biographical dictionaries were written in the Muslim world from the 9th century onwards. They contain more social data for a large segment of the population than that found in any other pre-industrial society. The earliest biographical dictionaries initially focused on the lives of the prophets of Islam and their companions, with one of the earliest examples being The Book of The Major Classes by Ibn Sa'd al-Baghdadi, and then began documenting the lives of many other historical figures (from rulers to scholars) who lived in the medieval Islamic world.[2]
By the late Middle Ages, biographies became less church-oriented in Europe as biographies of kings, knights and tyrants began to appear. The most famous of these such biographies was Le Morte d'Arthur by Sir Thomas Malory. The book was an account of the life of the fabled King Arthur and his Knights of the Round Table. Following Malory, the new emphasis on humanism during the Renaissance promoted a focus on secular subjects such as artists and poets, and encouraged writing in the vernacular. Giorgio Vasari's Lives of the Artists (1550) was a landmark biography focusing on secular lives. Vasari made celebrities of his subjects, as the Lives became an early "bestseller". Two other developments are noteworthy: the development of the printing press in the 15th century and the gradual increase in literacy. Biographies in the English language began appearing during the reign of Henry VIII. John Foxe's Acts and Monuments (1563), better known as Foxe's Book of Martyrs, was essentially the first dictionary of biography in Europe, followed by Thomas Fuller's The History of the Worthies of England (1662), with a distinct focus on public life. Influential in shaping popular conceptions of pirates, A General History of the Pyrates (1724) is the prime source for the biographies of many well-known pirates.
