Art Gallery Website

I need a art gallery website with a shopping cart. I will be selling prints of photographs I have taken. There will be options to buy different size prints and different frame types. Ideally the site will list the pictures like a gallery but then the mouse is moved over the image it must expand with a little description. If this is not available then a regular thump nail with description will do. It can be a template but must be nice looking. Needs to look professional and artistic. Please post a link to a sample site showing what I am looking for.
