I would use an image map on a polygon with the once keyword.  If the
bitmap tiles, putting it on a plane without the once keyword can work. 
Use type 0 for planar image mapping.  If you tile the bitmap on a plane
the once keyword is not needed.

polygon
{
...
   pigment
   {
      image_map
      {
         png "yourfile.png"	//there's also tga and others (sys for
system specific format such as bmp for windows)
         type 0			//the default, so it doesn't need to be typed
         once			//makes one copy of bitmap cover the whole polygon
      }
   }
}
