I am in the process of scanning some old slides of 60s to 90s and
wondered what the optimum size should be for posting on this N/G. They
will be scanned at about 300dpi.


640X480 is a dandy size for initial viewing. If folks want larger
prints for wallpaper or suck they will ask. They are never shy.

May I add that the size that you suggested should be at ~72 dpi
resolution to keep the file size smaller for the web. Monitors cannot
display the 300 dpi res any better than the 72 dpi res. The 300 is good
for printing.

Yes for posting that is OK, but not for scanning. A slide is about 1 inch
by 1 inch, so at 72 dpi you would have only 72 dots across the image. So
scan at 2400 or 4800, and then sub sample for posting.

Dedicated slide scanners for home use usually use 2400/4800/9600 dpi.
