Use map_type 5.

Create your torus with major axis equal to 1, because that's where the 
map_type 5 pigment radiates from, then scale it to the size you require 
after applying the pigment.


difference {
   torus {1, 0.6}
   box {<0,-1,-2> <2,1,0>}
   pigment {
     image_map {jpeg "test.jpg" map_type 5}
   }
   scale 4
}
