I wanted to email someone a picture that was 467,007 bytes.  (The
picture was from a newsgroup.  I did not take it.)  I thought that was
too big so I experimented with resizing it with PhotoImpact 4.2.  I
discovered that if I just loaded it and re-saved it without reducing
its dimensions, it went from 467,007 bytes to 37,341 bytes.  I have
PhotoImpact set to use "Best" generation quality.

When I look at the pictures, I can not see any difference until I zoom
way in.  Why is there such a huge difference in file sizes
(12.50654776 times)?

If there is another newsgroup where this question would be more
appropriate, please let me know.
