InterfaceLift is a place to go if you need some wallpapers for your desktop or even for your iphone. If your still using Windows XP then you can also download themes and also icons if you need those. The quality of the wallpapers is great and you can even choose the screen resolution before you download so it will fir perfect on your screen. I added the wall paper of the one I downloaded to give you an idea of the quality or just an example and below that is the link if you want to go check it out.
