I does take rather a long time to load. You could improve the perceived speed by NOT preloading all the larger images.
This http://www.wpdfd.com/wpdslid2.htm shows you how to load up pictures in the background while the reader is looking at the previous one. It means that the slideshow has to be sequential and not random acesss, but it's a lot faster. You would have to dispense with the thumbnails to stop random order access.
