I really love your image gallery and I am using it on the website where I post images of my kids (for family & friends).
I would like the site to be password protected and users to be able to request a username/password. I am now doing this with an external PHP script, which authenticates the users and then lets them continue to the correct page. This is of course not completely hacker-proof.
As there already is a user section in ImageVue, I would love to see that people could register themself via the script and that I could "approve" the users and allow them access to certain photo folders.
