There are a few great desktop wallpaper sites out there, and many crappy ones—but a new one (to us) called Social Wallpapering goes into the good pile. Browse through thousands of eye-catching images for standard monitors, widescreens, and dual monitors. The minimum resolution at SocWall is 1280x960, and all images are categorized and rated by users, so the "Most Popular" list is a good bet. (Get to it under the Browse menu, Everything.)
