An excellent source for free backgrounds, sorted by user rating. The images are available in all common resolutions, from 2560×1600 down to 1024×768, and are very diversely themed.
I was personally looking for 1280×800 resolution pics for my laptop and I found 78 pages of them! It also has section marked as PSP for wallpapers for PSP. The wallpapers I found were mostly scenic.
I just found this website for Brazilian wallpapers, they’re the best i’ve seen on the net!

The website pointed to by ‘anonymous’ (above) contains partial nudity and the pictures have mediocre resolution.
Yup, that’ll do it. You have my apprcieiaton.
