wrong.
first 15 spots are payed, so we can't count them. the rest are accepted bcause they're "clean" (they have 2 links or less , no more than 1 banner).
this type of gallery:
http://www.wedesignxxx.com/html/galleries/gallery5/
combined with a half page add ( usually a 600x400 banner) converts best for me but not all TGPs list it with the big banner.
