Images produced using the rendering engine in Poser should go to the Poser Galleries.
Everything else should go to Mixed Medium or their prime application category if the uploader
uses a different  rendering engine other than Poser.
porthos suggested the mixed medium earlier.
That's fair dontcha think ?
That way there is no confusion and someone new can see the differences between
the Poser engines and those images rendered with other applications and spend their
money on the application that best suit their interest.
