Gallery script with registration/view pic function?

I’m looking for a gallery script similar to the one on the sites listed below that I can incorporate into my own site setup. 

I want a gallery with numerous albums, when the user clicks an album they can view the thumbnails but when they click on the thumbnails they cannot view the large size picture unless they are logged in using their email address as their username, and a password that they chose in the registration process. Please advise to obu@hot24seven.com.Thank you in advance.

Here are the types of galleries i want to create with user registration to view large pics:
