Make Gallery accessible by specific email addresses only
I have a gallery that I want to make accessible by specific email addresses only. The client is sharing the link with others and I want to prevent that behavior without having to confront them after the fact.
I realize I could set a password, but they'd easily share that and it would still allow access by new email addresses. I also realize they can just tell people to log in using their email address to get access, but I think that's less likely to happen. It doesn't have to be foolproof...just difficult enough to where it feels like they have to cheat the system to give access to someone else who shouldn't have access.
