Shakes head... Not sure where you get the strict from...
The TGP2 rules are gallery builder friendly. You can see them
here
You can build a gallery with 5 linked thumbs, 5 links or more (or a fairly reasonable amount) to sponsors on the gallery page, put the big pics on html and have a couple of links to sponsors on each of those big pic html pages.
All of sudden you've got a 6 page site with 15+ links to sponsors and will have only posted 5 full size pics. (and if your scratching your head, think Google)
Try that with a tgp1 gallery or a linklist submit and see how long it is before you get kicked to the curb.
