Richard,

I finally got around to trying your suggestions regarding changing an 
image file's color depth.  I'm not sure what the syntax is. Here's the 
exact line of code:

    export img myImage to file myFilePath as png

I've tried inserting "as raw" or even just "raw" just about everywhere I 
can imagine in that command and I always come up with errors.

Your other suggestions are working out really well.  I'm especially 
having fun 'exporting with palette'

Many thanks!!!
