I must admit that the thumbs that showing up in the left  frontpage navigation, are almost nude as well. Better said "eye catchers". Most of the time they showing up with less clothes. So I see no difference in there, a real picture or a poser nude model. Their bikini's are just like a "rope" not sure if that is the good word for it !!  And I don't see that as clothes to be honest

Just my thought about the nude thumbs
