It's "kinda" real simple.
Make Audio Slideshow ó Combine the power of AppleScript, iPhoto, iTunes, and QuickTime to create slideshows with background audio! Select a track in iTunes, then drag images from the iPhoto window onto this droplet. The two elements, the MP3 audio file and iPhoto image, will be combined in the QuickTime Player to produce a movie! Double-click the droplet to set preferences for the slidwshow width.

and d-load the last script. I think that will do it for ya...
Have fun...
