EDIT: I see you already know about the upload warning. Well. Ok. That being said: the only option seems to be to ask Staff to disable image uploading from everyone except users with a certain usergroup (you could potentially make one that does nothing more than allow image uploads, and give it to all users that can be trusted). Other than that, this seems like a user problem.
