Basically, I want to upload about 10,000 family photos that have been organized into folders according to names of the people involved. What I'm looking for is php driven software that allows me to put passwords on each of the folders initially and then allow the family members themselves to manage their folder by adding additional username/passwords that they can add and remove.
I know php so I can make this if need be but I'd rather not reinvent the wheel. Also, if this can be done via script + htaccess that would be fine too.
