Here's a new one for ya.
www.gumgum.comStill in its infancy, but kindof interesting. I guess its for mainly editorial photos (although they do have shots of flowers and brides). It's a viral type of photo licensing. They host it, websites license it, and they charge something like .20 or .25 per 1000 views. If anyone tries to right click the photo, they get licensing information.
I checked a few questions on their blog that they haven't responded to... like percentages. Duh.
Not that I have any paparazzi photos... but it's interesting nonetheless.
