   Hmmm... I don't know if I'm understanding correctly. I've done:

   #declare f_im=function{pigment{image_map ... }}
   texture{
    function{f_im(x,y,z).gray}
    texture_map{
     [0 t_metal1]
     [1 t_metal2]
    }
   }

   were t_metal1 and t_metal2 also use the same file for the image_map. 
So I used both a function and the image_map keyword...
