The only thing that I think this community might be able to help with 
would be the addition of a watermark to your image (cryptographic and/or 
visual).  I am certain that this could be added at the PHP/Mapscript 
layer, and there are probably other places as well.

It does not solve your problem (PrintScreen, PicturePhones, PenDrives, 
floppies, all are still a problem), but it might give your legal team one 
more tool they can use to enforce a legal solution.
