I've been aware of this site for several years. It's certainly unique.
I think it's worthy of being linked to your page. Some of his material may cause discomfort for some, particularly his depiction of the naked Christ. But that's historical. The point of Roman crucifixion was to inflict the maximum pain and shame on the "criminal," and nude crucifixion was a logical move in a culture that was highly body-modest (Jews).
I haven't found anything in his scholarship to argue with, and there's certainly nothing pornographic.
Well, I suppose he was the only one willing to pose nude for it. I'm sure if he wanted to, he could get some volunteers from the naturist group or college art nude model to pose for him.
He did a good job posing as the replacement characters however.
