Hey there,
A simple method to get some free traffic and links to your site! A website I found whilst browsing stumbleupon called nsfws.com allows submissions to there website. When submitting images to the website you can add a click-through link hense traffic/backlink.
The click through is on individual pages and your images will show up in the main categories after approval but the link is active when pending approval.
To show you i managed to get a clickthrough to GFY.com on:
