Are those 10% who report pain are the same people who are more
succeptible to suggestion than others? Have anybody tried to compare
reports from informed and non-informed groups of subjects? In other
words, does this picture cause pain when people are shown it without
saying that this *is* a *pain* picture?

BTW, the site is there. I did not feel pain but maybe I was looking not
long enough :-) I saw the pseudo-colour though.
