WARNING: this photo is graphic.
It is also very, very much unconfirmed. It comes from a father who purports to have received from his Marine son. It was uploaded onto the Pickchur site (which is crashing at the moment from strain) here.
You can see a copy here.
You can tell that the photo is itself a screenshot of a computer on which the alleged bin Laden photo is displayed inside image viewing software.
Again, very much not confirmed.
UPDATE: From a reader, another version of the same picture can be seen here.
UPDATE II: It now seems all but certain that this photo is a fake.
