There is nothing wrong with image maps in isosurfaces specifically, but
there are general problems with isosurfaces.  

Concerning heightfields: It's a known bug in current 3.5 beta that png
output with 'hf_gray_16 on' is broken, apart from that i see nothing
preventing you from creating a smooth heightfileld, if you post a sample
(in p.b.i.) to show what's wrong i can say more.
