The lady who runs the site is very meticulous about her research, and has been careful to only show her readers what she can prove, and she has other photos that are so remarkable, most would scoff at them. (I've seen some of them, they're pretty cool).
Mediums can produce most anything on film and digital media. It's a FACT.
Thing is, if OTHERS can see the see the same phantasms standing in their general vicinity, then do you ufos really EXIST? What is causing the phenomena?

As for Randi's 1 million dollar challenge; you have no idea about the guy, and his history working with researchers. He has a horrid reputation as a pedophile. Keep your kids away from him! Besides, most mediums or those who can break the rules of science as we know it from the Dark Ages, (which include the last decade), WON"T work with any negativity because it stops the free rolling of PSI.
I know PSI is not what you want to hear, but it IS a part of the ufo phenomena whether you want to admit it or not.
