The question would be, "What is a well-doctored photo?"  Just putting a new 
head on somebody else's body might be detected by things like lighting (the 
sun is on the left but the shadowing on the face doesn't match with that).  
This is essentially how the Gulf Breeze photos were shown to be hoaxes (the 
supposed alien craft was shooting out a beam of light, but the light and the 
craft were not causing a reflection on the nearby car).  Of course, somebody 
knowledgeable in such matters could also correct for that sort of thing while 
doctoring the photos.
