It's a picture from an old notorious autopsy video (I think, although I haven't seen it in a long time). They tried to disprove it all kinds of ways by looking at everybody and everything that appeared in the video and checking it for credibility with regards to the time period in which the video was supposedly shot and the clothing and whatnot, and they didn't manage to, but you can't really prove it's real either. Truth is, if anything was found, with or without credibility, it'd be instantly dismissed by the public at large as fake simply because of the massive amount of content that has already been faked in that department. Is that video real? Maybe. Probably not, but hey, even if it were, it doesn't really effect... anything, so, in that sense, it's irrelevant.
