Tanya Hooker - repost

My sister is an artist and I am helping her to find a good solution for a website build. She needs something very simple to display her work. She would like to show her work in a number of different galleries. Each gallery should have decent sized thumbnails that can be clicked on and enlarged in order to see the detail. When the the images are enlarged they should be accompanied by the details of the painting - title, dimensions. Once the website has been built, she would like to be able to manage the website herself with my help. I have a attached an example of how she wold like one of the galleries to look. The rest of her work can be seen on her current website, www.tanyahookerartist.com. Most of the content management will be done by me so I meet some technical support for a little while.
