Windows 3.1 says:
Sorry to burst your bubble, but unless someone can confirm otherwise, I don't think it would be possible to be able to determine the creator of a JPG image. The meta tag data for them is stored separately by Windows and does not persist across multiple systems, and I don't think there would be a way to easily read a GIMP/Photoshop/Photofilter/Paint.net applied comment (nor do people use that feature often anyway).

This was a bad suggestion because it was exclusively suggested towards a certain type of creators. Not thinking of modmakers, in-game pictures/models, and any other person who should also be rewarded in the same kind of way.
Don't try to argue against this, I know you'll say "but screenshots are only visible on mania-exchange, other stuff should be credited in the game (outro etc.)", but I don't recognize that as a valid argument.

And custom models are in my experience not used much, really need a box for something that is not used by 99% of tmx:ers?
Space says:
maybe also add a possibility to show the screenmaker? on track uploading, just small checkbox "screen by:" and textbox where you can enter user ID.
