I rarely rate images, even if I comment. But when an image of that quality appears, there should be some way of drawing attention to it. There are so many images uploaded every day, it's hard to slog through them all, and things get lost in the sheer volume. CGTalk has a good, but somewhat biased way of doing it: a Choice Gallery. Work is submitted, and acceptance is based on the admins decision. The Poser Forum here has Staff Picks for each month spotlighting excellent renders. Other than splitting the "most viewed" and "highest rated" into 'Poser' and 'everything else', I'm stumped.
