most of this has been covered, so I'll just throw out a little more on the subject.
Look at it from the B&Gs perspective, do they want someone they didn't hire to have their images on your site? Did YOU get a model release?
If a customer sees images from the same wedding on each f our site will they be able to figure out who was the hired pro? Some pros require wording that you were hired help for the shoot.
I would not play the model release card since most Pros have a model release from the BG but they don't have one for the dozen of other people in the pictures they take (MOB, FOB, bridesmaids, etc.).
So while the Pro has a release for 2 people he is liable for the other dozen of people if we're going to use the model release as a cover.
Now in weddings people normally don't bring this issue up since it is a joyous event but if were going to bring up the strengths of the model release we have to look at it's weaknesses to. We have to acknowledge that there is great strength in it and you would have to get one done for everyone if you are going to claims it's powers.
If the Pro did not have anything in writing I question his business sense. Especially since there are ton of legal precedents to the work for hire trap (such as the link I previously posted).
As far as looking at it from the BGs perspective if they are worried about pics getting online they need to talk to every guest with a PS and cell camera and tell them not to take pics and put them on MySpace.
