Kind of a bridging problem I think

[AlbertaXchange]

I have an existing home made site with its own login stuff. I'm seeking a way to allow users to access their pix without having to sign in again to Coppermine.
EG. JohnDoe has signed into my site and wants to see his albums by clicking a simple link. if JohnDoe does not have an album already it will create one and allow him to upload pix without re-registering into Coppermine. Once JohnDoe has an album(s) other users can see his albums from his profile page.
Hopefully this isnt too confusing. I have the image of what I want to do in my head and might be having problems relaying it here due to working on this for a few hours and its almost dawn here LOL.

You'd have to come up with a custom bridge file for your app /authentification scheme then by taking a look at the existing bridges, figuring out how bridging works and modify the bridge file that resembles most your app.
