these are two different categories of problems.  

fake photos are not of the provider; I've been caught by them several times.  there is one provider currently advertising who uses several different sets of photographs, all of them not her.  

misleading pictures are not fake but don't show enough to get the correct idea.  for example, there is a provider whose photos are clearly real but they tend to show her as athletic and slim.  she is neither of those but once you've seen her it is obvious that the photos are her because of the hair and other parts showing in the photograph.  

there is a third category: old photos.  these are photographs that are of the provider but out of date in that she has gained weight or something else has changed so she is not as attractive as the photo implies.

Check out the pictures at the link of porn stars with and without makeup.

So even real pictures can be highly misleading.

But if you paid to see a movie and all they did was a bring in a television set, you'd probably be disappointed.
