The community is one of the most important things that keeps this site alive. So why not make community members more involved.
I came-up with an idea that might catch the attention of the site devs/admins.
The idea is to let the users vote for the wallpapers that get featured on the homepage (weekly). And just for the sake of preventing repetition, if a wallpaper gets voted one week, it's no longer eligible to get voted again for a month (or two).
Edit: Obviously, everything on the homepage should be SFW, right?
