CMS based artist portfolio site with automatic slideshow

I am looking to work with you to build a small artist portfolio site. It will be a requirement that the owner of the site will be able to edit text, create/edit/delete galleries and the images within the galleries. Images will play in an automatic slideshow without thumbnails or navigation buttons. I will provide you will specific designs and details in a layered PSD format. I will also provide all images that we would like to launch the site with. I am open to suggestion on the appropriate CMS platform on which to build the site, wordpress would probably be ideal though.
