You do realize that the image in your first link wasn't rendered in Poser at all? It's a 3dMax render with the Girl.  Anyway, you might check over at Deviant Art. I've been posting over there for two reasons. The first is the option to have a watermark added to image on upload (a feature that I wish Rendo's gallery had), and that you can sell prints of your work, though I haven't sold one yet, so it's not a very strong second reason.
