Even just adding a checkbox to the listing procedure might cause people to stop and think; something along the lines of 'if you are using an image in your work which is not your own (eg Disney etc etc) please confirm that you have the necessary license to do so' - wouldn't take much coding I don't think?
It's not going to stop the hardcore copyright stealer but it might help stop those who simply don't realise it's wrong.
