I have found tineye has become totally useless at returning matches.  Instead, I did a google image search and it revealed that the photos do show up.  All over the place.  They belong to an actress with a social media presence on imdb, linkedin, and her own personal website, among others.  Since I don't want to either out the actress if the Eros ad is really hers nor add to her woes if's not, I won't publicly identify her here.  (But you can do your own search of the pictures and see the results yourself.)

I will add this, though. It is one of the dumbest uses of a photo that I've ever seen on Eros regardless if it's actually the provider's photos or not.  The single review states that the photos are real.  If this is true, it's a great way to kill an acting career.  Because searching on the photos returns results from the professional sites mentioned above right next to that of Eros.  I fail to see how this could be a good thing for one's legitimate acting aspirations.  And her imdb credits list current productions, so she is actively acting.

If the photos are not actually of the provider, then the provider should definitely be worried that karma is gonna bite her in the ass bigtime if the actress ever finds out that her pictures are being used.  Either criminal impersonation or a civil lawsuit could be in the offing.  What I find really surprising is if this is actually the case here, how could the actress not have discovered this and taken steps to correct it by now? Professional people with public personalities should do their due diligence and make sure their online presence reflects favorably.

Thanks for the help. I did the Google image search and saw exactly what you're talking about. I will definitely stay away. Too many things don't add up. I really appreciate it. You saved me from a potentially catastrophic mistake.
