It's not meant to be sacriligeous, but rather to prove a point. I've always found it amusing how people find images of Jesus in grilled cheese sandwiches, on walls, or whatever, but never in, ah, "compromising" locations. What, God didn't make anuses? How can it be sacriligeous or somehow "wrong" for Him to appear there if his father God made it? Shouldn't we all line up to kneel before His image? Or is there something wrong with my logic?
