I believe that your picture is real as well as the all of the pictures in the link. The gallery appears to be from one of the karups mature ladies' websites.
I did a google image search on this picture and there is a thread from another forum that says "Patricia Richardson - faked" All the pictures in this gallery have this lady, Patricia Richardson's face photoshopped onto busty ladies bodies. Definitely not Miss Richardson.
Another blog that is in French has her name listed as "Catherine" Most of the pictures are available here ...
