How is a hash of the image supposed to prove anything about when it was created?

You post it publicly somewhere that has a timestamp. A blockchain would be best because it can’t be tampered with.

That proves it existed at a specific time in the past, not that it didn’t exist before that. What’s stopping a hash of the Mona Lisa on a block chain with today’s date?

It also doesn’t materialize ponies out of nothing. It can’t do everything, but surely you can see that there are a lot of situations where being able to say with confidence that “this picture existed in exactly this form at exactly this date” is a super useful thing?
