I posted the link over in the Computer Talk forum. National Geographic has hundreds of their photos as wallpaper free for the taking. Lots of flower, bird - some awesome hummingbird shots, animal, landscape shots.
Want some gorgeous computer wallpaper from Nat. Geographic?

Thats the Nat Geo link. Stunning!! Good to see the everyday digital people have not taken over photography, there's still a place for pros.
