| Love Wallpapers (1024x768)
Images used as computer wallpaper are usually raster graphics with the same size as the display resolution (for example 1024x768 pixels, or 1280x1024 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. 2560x1024) for displaying on multi-monitor computers, where the image appears to fill two monitors.
Smaller images can usually either be centered or tiled (repeated) to fill large areas, and depending on how skillfully the wallpaper was created, the tiling effect can look reasonably good. However, if the join is too obvious, or the image repeats too many times, it can appear to be very redundant.
With the increase in color screen mobile phones, wallpapers are starting to appear scaled to their lower resolution. These are often sold at a high profit to telephone users, although some phones have software which allows images to be uploaded from a computer. Mobile telephones with cameras can often use images from the camera, or from a received image, as the wallpaper.
Wallpaper styles are as varied as people themselves, using photographs, drawings, 3D renders or abstract pattern with complex gradients. It can be useful to have plain areas so that icons can be clearly seen atop the wallpaper.
