I've been a reviewer for some time now and it keeps amazing me how alot of galleries just get wasted because the ones who build it don't put the time or effort to build a good gallery, that's why i decided to TRY and explain to you gallery builders how you can make a good productive gallery.
First - General design.
The main thing on your gallery is the thumbs, NOT the sponsor. If i open a gallery (to review) i want to see a gallery where the thumbs are the main thing. I don't want to scroll down to see that first thumb either. The design should not be "messy" (example:
http://www.indiandelices.com/1/india5asian115.html), put some time in it and make a design that is worth looking at. Don't make it a banner farm, i got my own simple rule for it, 12 thumbs or less, 1 sponsor banner, 15 or more, 2 sponsor banners. A text link often works better then a banner people, keep that in mind. Your design doesn't need to be "flashy", i would rather list a simple clean good design then a flashy design.
In a few words, try to make a clean design, not messy, where the thumbs are the main thing.
Second - Thumbs and Pictures.
Thumbs: try to make high quality thumbs, thumbs that are scrambled or reformed won't get listed. Some designs are good but won't get listed because the thumbs are bad quality (example:
http://www.sexnurse.com/tgp/130mar6.html).
Try to resize those thumbs so they all have the same size, it will look better on your general design. Some galleries have thumbs with different sizes so the gallery in general looks messy (example:
http://www.xthumbs.net/gall/xcathy208009.html), if this webmaster would have made all his thumbs the same size i would have listed him or have given him a higher listing. Don't make thumbs that are to small (example:
http://fuckpicz.com/galleria/hardcore240blowjob123.html)
Pictures: Very simple, see that they are good quality pics, not to big of size (between 25 and 100 kb).
Don't put to much pictures on your gal!!!! Some people submit galleries with 25 pictures on them, i won't list it. 12 Is minimum, 15 is the best, 20 is the maximum.
Third - Description
I won't even look at a gallery if the description isn't any good. Don't submit a description like "naked woman", people know they aren't going to see a disney cartoon. Try to describe what she/he/them are doing, something about the clothes, something about the niche, whatever.... aslong as it explains the gallery.
Fourth - Submitting
Heh, submit by hand people. Most of those auto submit things will get you banned anyway. READ THE RULES before you submit, don't think "let's try it, even if i don't comply with the rules".... that WILL just get you banned eventually. Don't submit 10 galleries to the same TGP in one day, you are not the only one that is trying to get your gallery listed, if you do this, you won't get listed actually, and you might get banned.
So that's about it, i hope this helps. If you put maybe 5 to 15 more mintues in making that gallery you could have 300% of the traffic you have now.
If any webmaster or TGP owner wants to add something, please feel free to do so.
