If I have a problem with photos or anything else, I will talk to the booker. It's called professional courtesy. And they return the favor. I've had bookers tell me, photos of X are just representative because the girl doesn't want to put real photos online (an understandable request). I've also had bookers tell me, A has changed her name to B, or X is also working under the name Y.
No need to complain here if you have good information flow from the source. Talking to a booker is much more likely to get a problem fixed than posting anything here.
