How important are author photos & bios to you (Poll 1: Non-fiction)

Really important: I never buy a book by a person whose photo or bio turns me off.

Photo is not important, but the bio is: I'm looking for credentials.

I look at the photo & bio but they don't influence me very much.

I often buy a book based on the author's photo.

I never look at them or read them.

There are author photos & bios on books??
