Is that the alternate AF1?
The photo appears to be AF2, but is identical to the acft behind it. (How many AF2s are there?)
Many say that Q is some kid in Japan. If so, how did he obtain a photo from an aircraft in front of AF2 on a runway? We all know that when those are on a taxiway, nothing else is moving at that airfield. Nothing except AF1.
Was that photo taken from inside AF1, or another AF2? No way to tell.
But it was taken by someone with extremely high level access.
