I dunno, spiders do scare the ***outta me, but pictures of them don't effect me because I know it's just a picture. The worst thing I'd find is a Wolfe (sp?) spider where I live, so I'll never see one of those things unless I go to a zoo, but I avoid the insect/spider area like the plague.
I can think about them, read about them, even not bad at pictures of them. It's when they *** move >.> just that it is moving freaks me out.
