You can also go the Wordpress template rout.
WordPress › Blog Tool and Weblog Platform and get a "theme" here:
Wordpress Themes
The themes are easily changed to suit your needs - just pick one that is close to what you're looking for and you can add a gallery and various other nifty things. It's all handled through your browser so you don't need a web design program. And it's free.
Wordpress was originally designed for Bloggers, but it's been used by businesses, photographers and artists too.
Just a thought.
