I want to map my color aerial photo on a height field. When I do it, the
image is tiled so that there are four images on the image map instead of
one. Can anyone tell me how to stop the tiling and get it to just stretch
the image map over the entire height map?

thanks

Try this :
height_field {
  png "plasma3.png"
  texture {
    pigment {
      image_map { png "plasma3.png" map_type 0 interpolate 2 once }
      rotate x*90 // lay X-Y image map down onto X-Z height field plane
    }
  }
}

You mean you're one the guys who started all this craziness ??? I got hooked
with Image Lab in 1993... I probably should thank you then :)

Follow Gilles' advice. Then, if you want to, scale it after the texture block.

Ouch! Please, binaries attachments (especially this size) are not allowed here.
Convert your images to jpeg first and post your scene files to
povray.binaries.scene-files.

My apologies, that was really dumb of me.
