I don't know what point you're trying to make with the story about your friend. On one hand you're talking about your pro photographer friend, and then you're talking about people sharing photos on Facebook. They're entirely different use cases. There are already "pro" photo hosting sites that blow the socks off of Flickr, Picassa, and Photobucket. I use SmugMug, but there are others. The top tier SmugMug account is $150 a year and out of the box lets you price and sell photos and prints and a bunch of other stuff. Unless your friend sells directly to newspapers or magazines, I would expect she'd know of these "pro" sites. If she depends on photo hosting to make her living, I find it hard to believe she considers photo hosting an "afterthought." On the other hand, when she's just taking some casual photos, why wouldn't she use PhotoBucket or FaceBook? There's a huge difference between, "look at these stunning photos I'm trying to sell" and "Here we are partying last night."
