Given that you have a perfectly normal Flickr album, such as "Jillian Gaye turns 21", you can use Flickr's high-level interface to "customize" the slide show, and then it's another one of those cut & paste operations — you simply embed the Flickr SlideShow into any html, such as this blog posting!!!
Once you "start" the applet (by clicking anywhere on the picture viewer), you have all the usual slide show controls — including the "Full Screen" icon on the far right-hand side. Conveniently, these controls appear only when you move the mouse into the bottom part of the SlideShow screen. And all this is all done with Flash! Does it work for you without having to download anything special?
