There is no way to verify the reality of a digital photo. For a while Canon marketed a camera containing a tamper-proof gadget which would digitally sign its photos. I don't think it sold very well or at least you don't see them in use. Fotoforensics gives you a few clues such as showing contrast lines which should not be there. Even so it's 50-50.
I would say it doesn't really matter in this particular photo for a meme. Fakery only becomes important when it's a news-style photo or the president's birth certificate and all that stuff..
