Looking for a CMS to use for a gallery

Just any suggestions for a cms to be used as a gallery, which I’m thinking is the best approach instead of coding a php gallery. It’s going to be a gallery that a client can upload his photos too and also categorize them in albums. Any help or other alternatives.

Oh and also, The CMS or other method must be completely customizable.

Ummm maybe Gallery?

Is gallery fully customizable though Through html/css and the ability to add jquery?

The client only needs to be able to edit the gallery and not the pages, so would you suggest going with a stand alone gallery script, such as gallery or zen photo, or use something like concrete5 or SilverStripe?
