Wow......those pics are good. Thanks for the link,

I can give you a number of ways to fake those pictures with a film camera, including repeat exposures, models, and messing during development. With scanned-in images the options for digital manipulation are numerous.
However, in a case like this the pictures are so poor, and the information so third-hand, that there's very little point in me commenting on it. It says the pictures were analysed by experts - in which case who? What did they find?
If there's a silence from 'debunkers' it's because it's very difficult to prove something or disprove something on the basis of poor evidence. All we can do is say what we think is probable given the available evidence.
