There is interior_texture{}.

I think you could make the normal texture{} completely transparent and 
the interior_texture{} your image map. It should be the first 
intersection on the billboard uses the exterior texture{} and the second 
interior_texture{}.

Aside: By default texture{} gets used for the interior texture of shapes 
too - if you only specify a texture{}.
