ID4 sent me the folling proof, or rather, reasons why he things this pic is a fake. ID4 is a freelance CGI guy who has worked on some great films (his name should be a clue), he knows his stuff.
Red: Shadow from chimney is not consistent with chimney position and shape of hill
Cyan: Again, shadow is not consistent with anything in this picture.
Blue: gate has almost no texture
Over all, this is NOT a photo. It IS animation. The JPG is not clear and not lifelike.
He also showed me how easy it is to make a pic look realistic.
