There are three males in the pics. One of them has to be the infamous Abu Ahmed al Kuwaiti (aka Maulawi Abd al-Khaliq), the courier whom the CIA had been hunting for years and who broke the bin Laden cardinal rule of talking about aQ operations on a phone which lead the US to his doorsteps.
The other who looks remarkably similar in appearance must be the courier's brother - who was reported to be living in the compound and also killed; the last one has a considerable resemblance to bin Laden and is likely his son, though I heard Anderson Cooper on CNN say it was bin Laden himself earlier tonight.
These photos all came from Pakistani sources (didn't take long for Paki govt corruption to rear its head, did it?). It cannot be ObL unless the photo came from US sources. Conversely, the other ones with the time stamps could not have been taken by the US.
