Instead of clipping a plane you might try simply applying your image to
a flat box instead. For the sake of learning how to use image maps let
me give you my standard format example:

box {-0.5, 0.5 // a unit sized box
 pigment {
  image_map { sys "image.bmp interpolate 2 }
   translate -0.5 // center the image to the box
 } 
   scale <1,1,0.1> // scale box and image together to your size needed
  translate <somewhere>
}

I always start with a unit sized object like the one shown and then the
object and the image can be scaled and translated together.
