It has been my experience so far, and from reading other peoples experiences that every time they met a provider who used a fake pic in their Ad the service was really bad or just a plain rip-off. (The exception to this were the Asian providers, where the girls sometimes did not match the pics and service was still good). With everyone else, white, black, latina, ect, the service was always bad.
I could be wrong, but so far I have not yet come across a review that said... "She used a fake pic, but service was great! Will repeat!" No Sir. Not yet read one of those so far. (The only time is when the providers were Asian, which I stated were the exceptions).
Even when the provider did not show her face, as long as it is her body in the pic, the service was on a level that would be considered good. That's not to say that all providers who use their own pics give good service. Just as a common rule of thumb... Fake Pic = Bad Service. At least it is what I have come across.
In last experience, where the provider used a fake pic in her Ad. I went ahead anyways. Wrong choice! It left me feeling like I wasted a lot of money. I have learned my lesson here. If the it's not the girl in the pics when I get there, I will just walk away. Immediately
