Todd of “What do I know” has released code (FLA) and an SWF with his slide show that he developed for the PGA Championship: Flash slide show source
Its a very nice project. It loads a list of the pictures from an XML file where you set your file names, random or sequential showing, and the speed of the crossfade. He has also included attributes for toggeling looping and setting image size in the HTML for the swf. (So that people without the Flash suite can use it).
All in all its a neat little app with neat code. Very nice work Todd!
