"In order to alert Pixels.com visitors about your promotion, your promotional print will appear on a special page of our search engine:
http://pixels.com/art/all/all/special+promotions
This page only shows active promotions. If you've ever felt "lost in the crowd" on Pixels.com, this is a great way to stand out. Each Pixels.com member can only have three promotions running at any given time, and as a result, the number of images that appear on this special page of the search engine will be quite limited."
