I´ld advise people to be careful about posting highres stuff.
Naturally a scene looks a lot better full size, but it may also end up on some DVD cover without credit or payment, and it´s not worth it.
Better to let people contact you if they want to use the image and let them pay you for the hard work behind it.

Just a thought. :)
