Yet Another CMS Question (for Photography Studios)

Hello,

I'm looking to implement a PHP-based solution for my photo studio that allows easy upload, easy organization of images, and easy customization in terms of aesthetics with RSS support.

Since the site should be simple and easy to navigate, Coppermine and Gallery are ruled out (unless there's a way to strip most of their functions?) Please help me find the right CMS for this site!

Here is a website that follows the similar site structure:

Please help! Thanks!!
