Basically, this would also help improve forum activity in those sections.
Anyway my idea is from the 1st-20th (or something), people post any graphics they want in any of the 2 graphics sections, the only rule being it has to be made on a computer (ie not photography, I guess drawings could be allowed, or maybe include both). And say whoever the graphics team are, they recommend ones for the "final 5". Then on 21st-27th people can vote for their favourite and then on the last days of the month the winner is announced.

Possibly also, instead of the normal "motm" for graphics, the graphics staff could again recommend people in a similar fashion as in the other idea and then users vote out of the top 5 etc. I don't think motm is fair in a section like graphics as some people might literally spam their own thread and make 20 threads of the same piece (a little exaggerated).
