The photogallery is a "section" within the CSK site. You can create as many photogallery sections as you need.
Each section can have independant security settings regarding who can view, edit, and add items to a section.
So you can create a section for one of your users and give that user security permissions to add and edit the content of the section while other users would not be able to do this. However, you could still allow all users to view the section while giving another user rights to add and edit content within the section.
It's just a matter of configuring the section and security. The gallerys are not "shared" for all users really. It's just that by default, all users have view permissions to a new section you create.
