Abby, you don't say what these on-line images are images of: e.g.,
photographic 35mm slides, book pages, 4x5 B&W negatives, ....
 
"Scanning" at 72dpi is probably not what you want to do, if you are
talking about digitizing 35mm slides; the overhead in setting up to do
the scanning is sufficient that by the time you've done all of the setup
you might as well invest the modest marginal cost to digitize at a (much)
higher dpi. And, in fact, if you're talking about 35mm slides, you'd be
hard put to find an easier/cheaper way than to use Kodak's PhotoCD process
via a commercial lab. You can post-manipulate those images to your needs.
 
Having scanned the item/image at a relatively high resolution, you can
begin to consider the various (lesser) resolutions to offer up for viewing.
Your decision(s) would depend on the audience, use, control you have over
rights, etc., and you could offer up various levels of quality right up
to the highest quality.
 
There's lots more to it, but this will give you the flavor of the issues.
 
(Discussions about resolution, dpi, displays, images, get very intertwined
and confused. Be really careful to always know exactly whose "dpi" you
are discussing.)
