Is it possible this is part of an official disinformation campaign?
They haven't got the time to make the series on a regular basis but have the time for this? And why bother. It's hardly a topic that's got the nation gripped. It's one or two fans who desperate for attention or who think they're getting one over on people.
The thing is though, while those photos may be faked, every bit of official information about the episode (particularly the DWM preview) supports the original leaked synopsis. (All the extra stuff that other people are claiming is in the episode, not so much.)
