My web site is Wordpress using a theme called Porfolio, which I have modified somewhat, from Dalton Rooney. I think he has wandered by APUG on occasion as well.

The theme can be found here:

He charges only $12 for it and it includes some fantastic slide show and image display coding, worth way more than that in my opinion. He also offers a free Wordpress plugin, Portfolio Slideshow which allows you to place a simple slideshow in any Wordpress based site.

Dalton provides support for the Portfolio theme on his web site and is very good about answering questions and such. I highly recommend it.
