Thanks for that advice Bob.  Have you tried that approach with slides? 
I guess it should work the same, but a problem could be scanning 
slides with sufficient resolution without going to an expensive 
dedicated slide scanner.  (Do those still exist?  I haven't seen 
mention of them for a few years now, not even ads.  Perhaps like so 
much else, they have succumbed to the mediocrity of the masses?)

Cheers, Phred.
