The isusrface tutorial in the official docs contains an example how to 
displace a planar surface with a function:

http://www.povray.org/documentation/view/3.6.1/73/

Instead of the noise function used there just use an image_pattern 
pattern function or image_map pigment function.  There is also a macro 
in the IsoCSG library that wraps an isosurface to be used like a 
height_field:
