Replace the sky_sphere with a large sphere, make it hollow and add  
no_image to it like this:

sphere{0,1
  pigment{image_map{hdr "..\kitchen_probe.hdr" once interpolate 2 map_type  
1}}
finish{emission 1}
scale 100 // make sure the sphere is big enough to cover the whole scene
hollow
no_image
}

Now you can add a sky-sphere with the image you want to show (or just use  
a background with a single colour)
