Well, I heard back from greenguy - he basically says "Where the hell did they get that idea?", hahahahhah.

And he asked me to post this from his letter.

Can you please go post a link to my rules for me:
http://www.link-o-rama.com/greenguy/therules.htm

And put in there:
Minimum Number Of Pictures For Picture Sites
Regular submitter: 24/site with 12/gallery
Trusted Submitter: 2 Galleries: 10/gallery; 3+ Galleries: 8/gallery

Crap, even I didn't know he allowed 8 per gallery if you do 3 galleries.

Anyway, I still think the optimum numer is 15 per gallery. 12 for the more expensive bought content.
