How to get traffic to a funny pics site

Ok so i bought ninjamediascript yesterday, i have posted a about 20 pics and starting to get some traffic from pinterest, tumblr and twitter, maby 60 visitors. I made a new fb page for it too.
I dont know what else to do please help?

You can use another social netwok such as IG and FB, for example.
Or you can add some text content to get more organic traffic to your site.

Besides what you're already doing Instagram and Reddit came to mind, Imgur (without Reddit), 9gag, maybe fourchan too, however you need to be smart about the promotion techniques, because they seriously hate spam.

I would just make fully engaging content without pushing advertisements or anything stupid affiliate product. If you do it right sponsors will want to come to you or you will get donations from loyal viewers (think about 1% of your total unique visitor audience will donate to support an ad free environment or giveaways or even deals).
