Hi Steve, welcome to
RP!
Have you checked out the challenge section of the site? We'd love to have you participate in those with us. There's also an archive that has a lot of images you might find useful.
I'm not sure how things work in Germany since I've never been there, but if you have antique shops the way we do here in the US they might be a source for practice images.
For anyone wanting to send you images who is on a dial-up connection, do you have an FTP site available?
(Also, doesn't Hotmail have a size limit to the attached files you can receive? I seem to remember something like that...)
