> Please explain to me why you posted suggesting otherwise.

a) I didn't suggest otherwise, I said that it is predicated on that assumption, about which I was undecided, largely because b) I didn't know better.

I read that thread 7 days ago, when the collisions were a gray blob or a clearly modified dog (to Lena) or clearly modified Lena (to dog). I hadn't re-read the thread in the last 4 to 5 days, when you demonstrated the natural looking collisions (second-preimage images).

Very impressive work I wasn't aware of.
