Then, you must be using the accelerated JPEG. Otherwise, it is painful.

When you select, reorder slides from the menu button, this SlideShow 
does roughly the same thing. The thumbnails are saved in a file called 
thumbs.st (Stored as objects). BTW, this may take some time (i.e. 
building all the thumbnails).

It shouldn't be very hard to write some code to move files between two 
SlideShows.

I got nothing there. Although, an UpdatingSketchMorph using morph's 
stepping features shouldn't be too hard to implement.

Peace and Luck!
