Here is a free collection of cool free smiley face wallpapers for you to use on your desktop. Feel free to download as many as you want and to use them at your liesure, the standard wallpapers are all 1600x1200 pixels in dimension, if you don't use that resolution then just get windows to stretch the wallpaper you want to fit the desktop, though they may look a bit odd like that on widescreen monitors.

If you're a webmaster I'd appreciate it if you uploaded the files you wanted to use instead of hotlinking to them but if you use Myspace or anything similar you can hotlink to the, right click and select properties to get the URL and then use that in the website that supports user customisation such as Myspace or other social networking sites!
