My rule is Seven to ten, with ten being the UPPERMOST limit, period. I've had visitors looking at pages (I was watching them while they surfed IMFDB) and they got bored when they ran into sections that had 14-24 images of the same gun. Even these brand new visitors exclaimed that it was ridiculous and they immediately navigated AWAY from that page. Now would any one of us WANT visitors to navigate away from the pages we built? Editing is a discipline, and for any of us who have edited a story or school newspaper or yearbook, you know that a good editor makes the hard choices and will remove obviously good (but unnecessary) shots.
It's like forcing someone to look at each and every screencap you did, whether they like it or not.
