    Have you tried the map_type option?
There are several image mapping types
type 0 - planer, type 1- spherical and there is also
cylindrical, toroidal, and maybe more I have forgotten.

For spherical mapping you would describe it like this:

sphere{<0,0,0>,1
 pigment{
  image_map{ tga "image.tga" map_type 1 once interpolate 2}
   translate<-.5,-.5,-.5>
    scale 2 }}

This should I believe accomplish what you are looking for.

If you have any further questions feel free to ask.
