V13 is right. To print a poster of decent quality, you need to be able to print at at least 600dpi. That requires very hi-rez images which would be prohibitive to upload. Not to mention, working with those files on your own computer can be prohibitive unless you have lots of space on your hard drive and huge amounts of RAM! And I think speedofdark did mention something about printing posters. Worth checking back through the archives if you are interested.
