You could look at the texture section in the POVRay doc
http://www.povray.org/documentation/view/3.6.1/331/

to simplify you put a pigment, it is ok
but ambient is a finish item.
pigment determines the basic color of an object on its surface.
finish determines how this surface reacts to light (diffuse, ambient,
reflection, specular.....)
pigment and finish are gathered in a texture block
sphere
       { <0,0,0>860
       texture{
            pigment { image_map   { gif "sun.gif"  map_type 1    }
            finish { ambient 1 diffuse 0}
// ambient 1 makes object "shine" (not lighting the scene but visible)
//and diffuse 0 make it not interacting with lights
       }
   translate <0,0,3000>
 }
