Images for the home page ... lots of people look through the "more images" as they are uploaded...
Why not place a vote system, a bit like the "hot or not" website but with a simple yes/no response to "is this image home page suitable?"
Once it hits a certain number of votes (say 50) and has the right ratio of yes:no then it appears on the home page?
It takes the work away from the moderators, automates the system, and gives more people a chance to get featured on the home page. As a premium member the exposure gained from it was one of the major appeals of the site in the first place. Now I'm lucky to get 1 out of 4 uploads featured.
