The National Geographic site has the best wallpapers! I usually end up changing mine every month or so because they have such interesting pics. They've got some great spring wallpapers to choose from this month.

See the pretty pictures at:

I use their pics also, but not just for the flowers but the other great mountain shots and I'm a polar bear lover and they have some AWESOME sots of them, so I have a lot of their pics saved and make them my wallpapers too!

I love it....thanks for the link!! It reminded me of a pic I took last year of our magnolia tree. I keep thinking I should enter it in the monthly photo contest offered by our newspaper.
