Penultimate Amazing
To me, a picture tells very very little. I will never be convinced that something exist based on pictures. Bring me hair, scat, or bones. I'll be converted instantly. Pictures tell nothing.
I would not consider a picture final scientific proof, perhaps, but a good, clear picture or series of pictures that cannot reasonably be consdered a picture of something else, from a trustworthy source would suffice for me to say "I think there's a bigfoot after all," and I think it would be sufficient to trigger a proper, all out scientific search.
