The butterfly is from a photo of mine in which I managed to carefully select
only the butterfly itself and then make everything else black. POV_Ray's
image_map syntax allows transparency. Here is how I did it:

box {< 0, 0, -.001>, < 1, 1, 0.001>
pigment {
 image_map {
  gif "black3016.gif"
  transmit 0, 1
  map_type 0 //planar
  once
  interpolate 0 //none
 }
}
finish{ambient .5}
}
