yah, submitting galleries is a great idea, however if you're going to do that, i wouldn't suggest perfectgonzo... yes all of their content looks amazing and they do have alot of nice tools however ALOT of webmaster use their galleries on their sites as well as sumbit them to TGP's thus making sales for perfectgonzo someone tough..
just my 2 cents...
good luck webmastering
P.S... if you want to try out a different site...
NS Cash has a tonne of sweet galleries and like 30 somethin sites to promote...
