It'a a difficult market. Work out the bandwidth on this situation
20k visitors a day view 6 pictures of 100k in 2 galleries on average for your site.
If my maths is correct that's 24Gb of bandwidth per day, and that doesn't include the html or videos if you include them (videos convert better). You've got to try to convince these freeloaders to buy something or you're just giving them free porn.
I think you need to lose the pictures and set up a traffic exchange or thumbnail gallery post site (TGP).
If you're submitting galleries to tgps, the name doesn't matter. If you are setting up a free site or a pay site, then you need a niche name like big boobs or something.
