***** An aside ****
I have been scanning 50 year old slides and they are coming out great
except for some dust particles.  I have been saving both huge TIFF
images and reduced versions that are JPEG's.  I have created multiple
copies on DVD and CD for all the kids, aunts and uncles.  I also have 85
year old negatives of family pictures to eventually scan.  I also still
keep the originals, the digital copies are easier to display.
