Get MegaPov 0.4 at http://nathan.kopp.com/download.htm , if you haven't already,
and use 'image_pattern' and I think you might be able to do what you're asking
about.  From the MegaPov HTML document is an example of it's use:

texture {
  image_pattern { tga "image.tga" use_alpha }
  texture_map {
    [0 mytex ]
    [1 pigment{transmit 1} ]
  }
}
