I tried following some of the links from DU and got nothing except claims of finding pictures that no one else has seen. It seems to me that if such pictures really existed, the blogger would have posted them or at least a link to the pictures on his web site.
What's even better is when someone posts a pic purportedly of Gannon, and it shows no identifying information as the face is not visible.
As seen in this thread by shpongled at post 85, which has finally been removed.
Or it's just a pic of shoulders upwards.
The links are out there, believe me, you really don't want to visit them unless you want to know all there is to know about Gannon.
