Seems unlikely these would be faked and they certainly don't look it to me. As another poster has said, there's a lot of checkable info there. If the picture is faked, DamienB, and indeed Capt. PPrune or whoever actually owns this forum, could easily and quite correctly be sued for libel. I'd be pretty pissed off if someone took a picture of my aircraft and superimposed it in this fashion, especially if it lead to a CAA action. That would certainly malign my reputation, such as it is.
