The first and fourth shots "could" be real, because the view of the print looks correct if you were standing right behind the girls.
BUT (no pun intended): the rest of the shots show the "print" at an angle, which would look *completely* wrong if you were on the other side of the girls looking at their behinds. So I have to call foul (or call photoshop) on at least the rest of the shots.

EDIT: Er, first sentance should read "The first and second shots..." Too many butt shots to look at, not enough fingers to count on
