Background map rendering

hi every1,
I have played around with Zbrush a while , trying to get the modelling , painting done. Now I want to render my model.

I have set up a background image (using Light | Background | Create …) but when rendering I always get my document background color.
I assume I have to set the render parameters, but I couldn’t find which one ?

thx

Light > Backgrounds will only be rendered using BPR (Shift+R).
