Have you ever considered turning one of your art challenge winners into a desktop image on this page? It might promote some of the challenges you do to give them the front page recognition.
The art challenges I used to run (they stopped because the last couple I ran had almost no participation ) were just for fun and had no winners. I have been contemplating holding a screenshot contest next month where the winning shot would turn into a wallpaper for the page -- tune into the Art subforum to see if this happens
