Stock photos make you look the same as everyone else.

They give you a website that says as Seth Godin puts it: "We're the same, we're the same, we're. . ."

He goes on to say: "Sometimes, we try so hard to fit in we give consumers no choice but to seek out the cheapest. After all, if everything is the same, why not buy what's cheap and close?"

You need images that show your uniqueness. Stock photos can't do that.
