I wonder if these images are all in the public domain.

Edit: Seriously, these are all personal pictures of people clearly visible. Isn't that question legitimate?

I agree, it's a legitimate question. I tried to search for a bunch of them on TinEye to see if I could find some original source for any of them that might indicate a licence, but none of the ones I tried came up with any results.

Very possible it's pictures the author of this tool took personally, which would explain why tineye doesn't know about them, how the author found them, and how they had the patience to annotate them all. Also, best to just assume copyright is all good, it's not like these photos are of military secrets or anything, no need for us to step in, I'd think.
