Nextgen private gallery upload

Greetings,

I apologize if I am posting this in the wrong forum, but I have looked around the web, and have not been able to find a plug-in or series of plug-ins that would do what I am looking for.

What I would like is to be able to have users register at my site, and then be able to create multiple private galleries (with no intention of these ever having the ability of being public) and I would like to use Nextgen, although I suppose that isn’t set in stone. The users would need to be able to upload new photos to their gallery, with the ability to add or delete photos at a later date.

Thanks in advance
