It's very simple, you seem to be getting so far and getting an 'Error' is that right. Most likely the pic your trying to put up is too big. In which case you'll have to reduce to to 100x100 pixels. If you don't know how to do that try looking for irfanview in altavista, it's a shareware file. It's the easiest picture editing software I've ever used.
Drop me a PM if your stuck.
