no, not really. the image still has to sell, it's sales first, then everything else second, but it is a good start. views, votes, comments, i'm pretty sure outside links and not just inside ones are also a factor. stumble might be a good way to get a few links to your page though. and get your name associated with your work, and that's always a good thing. i'm pretty sure they allow a description, make sure that's the first thing they read.
