I do not know the source of the pictures. What I do know is that the first person that I saw post them, well over a year ago, is someone whom I trust and who has actually been there and can personally attest to what the terrain is like. They are not that person's pictures, however. I suggest that you follow some of the links on this thread and the links on some of the threads linked to this one and see if you can find the source yourself.
