I also saw that on You-Tube. Some of those pics have been photo-shopped. It is obvious that #1 has. It is amazing what you can do to pics with photo shop. #4 has a face that looks more like a man than a woman.
A couple of years ago there was a guy that put up before and after pics on another site. They were obviously photo shopped and wasn't even a good job. His abs were phony looking. Everything had been enlarged about 20%. I was going to comment , but everyone was kissing up to him saying what a great job he did. So I didn't want to spoil the fun. I was wondering why someone would do this and he either had self esteem problems and needed praise from these guys or he was just having a good laugh at how he could fool all these guys.
