Like Galactape said, I use photobucket. Take a picture and upload it to your computer. Save it to your pictures(on your computer). Then open an account to an image hosting site, upload your pictures from "pictures" to photobucket(or whatever site you use), and then copy the one that says IMG. Paste that on your trade items, and when you click submit, go to you b/s/t list and you should see the pictures you posted!
