Help with adding pictures

ok i have been a member for some time now but have never been ableto add pictures to any of my auction. It would be really nice if some1 could help me out with this. I can get 1 picture on now but would liek to be able to move all my pictures, like you see on many auctions, onto 1 website (like imageshack) and then post that website. If any 1 can help me with this that we be really nice.
