There is a book by Richard Dawkins- I am me I am free or something like that, and it has a main picture of Richard standing naked and having a private part being covered by black rectangle but somehow my laptop back then was slow and when you scrolled it would temporary remove the square for a split second

Are you sure? I can't find any trace of any book by Richard Dawkins with a title much like that, and that doesn't seem like a very on-brand sort of cover pic for a book by him, and an image search for "Richard Dawkins book cover" doesn't turn up anything like it.
