I allow up to 4/day - prefer variation in page templates (= not all galleries looking the same!) and list almost everything except really sick stuff, cp, comix, and gay. "Teens" is usually a little crowded so I can't promise a listing, "Ethnic" and "Couple" usually have room left.
picXS.com has not that much traffic at the moment (~ 8k), but some good se placements, and my server has been changed yesterday which seems to help already, so I hope traffic will improve
