Welcome to the board
I get traffic lots of ways, by submitting galleries to TGP sites. Submitting freesites to LinkLists, getting free traffic from search engines, feeder traffic from linkdumps and traffic trades with other webmasters. etc. There's limitless ways to increase your traffic.
I prefer using gallerysubmitter.com for my gallery submissions, it's 100% hands off so you don't need to confirm emails or anything like that, saves time. You can also schedule all your submits (3-5 a day) for a whole month so you can focus on other projects as your army of galleries is submitted. Did I mention their service is FREE?
