Just thinking, it might be an idea to implement the kind of quality control in place at CGSociety. An artist can put anything they like in their own gallery but for their image to be included in the main gallery it has to be accepted via some moderator decision. I'm a professional digital illustrator but so far I've only uploaded a couple of images because of the general quality of the images here (bloody awful Poser things) because I'm wary of being involved with a site that seems to promote so many awful images.
I'm not knocking people who are making an effort, just the ones that seem to
post images with no obvious effort involved.
Anyway, just a thought :)
