If you haven't come across the TURBULENCE keyword yet, try it out; you can
distort the image_map in all sorts of interesting ways:
pigment{
image_map{jpeg "my_image.jpg} // or .jpeg
scale 5 // optionally scales the image before the distortion
warp{turbulence .5 omega .7}
scale 1/5 // returns the image to its proper size
}
