Occasionally I need to make rapid-fire slide shows of 600-2000 images with rocking backbeat.
I've used lots of packages. even fired up trial version of Final Cut Pro X..
There are SO many cheesy slide making programs out there.
Have had some luck with FotoMagico.. but even that is choking and crashing in Lion OS X environment. Or is at least very pokey..

What is the BEST slideshow making program out there?
I haven't tried iMovies yet.
