Scott,

I'm just finishing an animation program and Livecode has served us well 
as a platform for this.  We're not using different images for each 
frame, yet, but we're doing a lot of other creative things like rotating 
images, changing their dimensions and changing their opacity (fade in 
and out) and I'd be happy to share this with you if you think it would help.

We've had good results taking snapshots of images on the fly so you 
might consider doing this before you start playing your animation. This 
might eliminate your speed issues.
