  We did this not too long ago for Medical images to be
searchable/served from the Web. We decided on 90 (wide) x 60 (tall)
pixel thumbnail images and 720 (wide) x 480 (tall) pixel final images.
Our decision for the final image size was based on the final media that
the images were expected to support -- in this case it was on-screen,
multimedia projects. The thumbnails size was determined by finding the
smallest size that would get across the contents -- this is subjective,
of course.

You can see a sample of the database (with limited data) at

Hope this helps...
