Greetings,
The National Graphic Web Site offers free images which can be downloaded at no cost and used as computer desktop wallpaper.
I’m not a big wall paper fan. Computers are a tool to get stuff done, not decorate but I also realize that not everyone shares this opinion. For users who enjoy “beautifying” their digital environment may I suggest the National Geographic web site as a site from some incredible images.
National Geographic has long been known for the quality of it’s images which capture the incredible beauty of the natural world and the free wallpaper gallery is a wonderful sampling of this treasure.
There are actually two different galleries. The main wall paper site:

and a contest site where users such as you and I can submit pictures, like this one.

Enjoy
