Not accepting offline image and its continuosly loading in JS Fiddle

Hello Developers,

I have successfully used this package. When providing online image it works perfectly. When I use downloaded image instead of link, it continuously loads (skull,vtx - 8MB), it goes on loading and does not show image.uid

Code:

window.onload = function() {

  // create and initialize a 3D renderer
  var r = new X.renderer3D();
  r.init();

  // create a new X.mesh
  var skull = new X.mesh();
  // .. and associate the .vtk file to it
  // skull.file = 'http://x.babymri.org/?skull.vtk';  // online image link 
      skull.file = 'project/path/skull.vtk';               // downloaded image file (same as above)
  // .. make it transparent
  skull.opacity = 0.7;

  // .. add the mesh
  r.add(skull);

  // re-position the camera to face the skull
  r.camera.position = [0, 400, 0];

  // animate..
  r.onRender = function() {

    // rotate the skull around the Z axis
    // since we moved the camera, it is Z not X
    skull.transform.rotateZ(1);

    // we could also rotate the camera instead which is better in case
    // we have a lot of objects and want to rotate them all:
    //
    // r.camera.rotate([1,0]);

  };

  r.render();

};

Please guide me. Thank you for your help
