I only use my phone and mostly only when I’m at work (or home alone, no wife or kids). You don’t need to save the photos, just press down on the photo (like a right click with a mouse) and it will give you the option to search google for the pic, or copy the pic url which you can use on tineye. That’s issuing Chrome on an iPhone, don’t know about safari....I installed chrome so I don’t accidentally leave anything open on safari.
....but anyway, doing that, nothing turned up. The pics look legit to me. She also offered a 10min $100 session, could take a flyer on that to see if she’s real or worth it.
