I think you missed a bit somewhere. I don't suggest you sell event prints through our gallery. If you want to do that, sign up with PhotoStockPlus.com
. They have a complete system of pricing and ordering and you can password protect your galleries. Our gallery is merely for people to post their pictures for others to comment on.
As you say, you can't sell pictures for publication that contain recognisable people without a release. But the good news is that you, as photographer, would not be breaking the law, the publishers of the photos would be the ones in trouble.
