The link lists you are submitting to right now have a minimum of 30 pics, because you are using 32 i would say that is around the right number of pics to use on a free site.

Some people will tell you to use more, some will tell you to use less.

The problem with using more is that you actually give to much away to the surfer and we're supposed to be making them join paysites to get off, not get-off on our free sites.

The problem with using less is that many link lists simply will not list your site, cutting down the amount of traffic you will be able to get.
