Well, you write

 #declare MyImageFunction = function { pattern { ... } }
 height_field
 {
  ...
  function 256, 256 { MyImageFunction(x,y,z) }
 }

which is exactly what the syntax description in the docs says.

I don't see why one would declare an image and be surprised that is doesn't
work (as that is what your example tries to do) - it isn't possible at all
with any image map type and never has been...
