Quote - Sigh,Background pictures still doesn't auto fit to rendersize.They do fit to preview and Poser4, but not when rendering in Firefly mode.I wonder when this will be fixed.

After setting up your scene, delete the BG pic, save and exit Poser.  Reopen and go directly to Render Dimensions.  Set the dimensions, THEN load the fullsize BG.  Render.  It works.
