The Shoestring - Although not primarily a trash picking site, there is a dumpster diving section in which I've written a few articles. This site focuses on how to save money and live like a cheapskate, featuring articles by users. Check it out, you'll save a buck or two.
Image Shack - Not a site related to trash picking, but they'll host your images (up to 600 KB) for free! Just upload it and they give you the link.
Sigthor's Finds - A dumpster diver's photographs of his collection of finds. Lots of stuff ranging from electronics to food.
