Seems to me that there would be at least a few people out there that know enough about .jpg and other image formats to make a new 1 that would be close to jpeg without too much trouble. And how many people would actually pay for it anyway, even if people don't want to pirate it, most internet users will have no clue and just use it anyway. It would probably work about as well as the music industry trying to keep people from trading mp3's.
