277281 Photography Customer Login

We have a website already but we would like to make it so that we can create customer accounts that allows them to login with a username and password. We would of course like a admin area to upload and add to their gallery. I already have a flash program that creates gallery views of the pictures. What I need is a script that creates a folder for the customer and our admin area will have to be able to add pictures to that customers profile (folder) within the admin.
