Richard,

Have you tried using the pixMapID property? You may want to check the 
archives for the limitations of this (IIRC it may crash if you try to 
reference a stack which is not in memory), but...

set the imagePixMapID of image "snapshot" to the pixMapID of stack 
"someStack"

Then you could export the image?

Dunno for sure, but it may be quicker!

HTH,
- Brian
