Depends on what it looks like. I'm not being flip; I don't have a website but I visit many and for me the tone of the personal photo can sometimes influence my reaction to the site. Perhaps only because I'm a photographer I like to see the person "at work." I react most poorly to a pretentious looking shot or one too artsy for words.
Slightly off topic, I like to be greeted by a page that features a single photo and a bit of text that tells me where I am and how to easily get to the person's work.
Elaborate flash openings with complex unlabeled navigation features drive me nuts!
