Try that:

cylinder{<0,0,0><0,70,0>dia/2+.25
	pigment{
		image_map {
                jpeg "RE55s.jpg"
        once
	interpolate 4
		}
		scale <1/3,24,1/3>  // labelheight
  warp { cylindrical orientation z dist_exp 0  }
	}

}

Or make RE55s.jpg three time it's current width, with a neutral colour
for the extension.
