I renovated my photography site last night and published it this morning. I decided to go with Flash based Slideshow Pro which is very easy to use and has a lot of options to tweak the look. The downside to flash is that the default <embed> tag is not XHTML compliant. However, the W3C website did have a link to A List Apart which explains a compliant way to embed a flash movie.
