Deb Coates sent me a link to this tool - http://www.slideshowpro.net/index.php. Very nice tool for developing image slideshow using Flash. You need Macromedia Flash MX 2004, but it sounds pretty easy to use and once you have it implemented, it is all data driven by XML or an RSS feed from Flickr.

I really like the quality of the images and the user interface, specially the popup menu. I also like the tie to Flickr RSS. Pretty cool.
