I agree that this may be an update, probably to sharpen certain things that hadn't popped out earlier. If so, there is the possibility that they would change other things as well, hiding a message in the picture. I would bet that they might use steganograpy (credit goes to Mazin). All of the links to the old picture are low, so if someone is sure that they have the original, please post it. That way we have both of them here to compare...
