code: def largest_connected_component_img(imgs):
      """Return the largest connected component of an image or list of images.
  
      .. versionadded:: 0.3.1
  
      Parameters
      ----------
      imgs : Niimg-like object or iterable of Niimg-like objects (3D)
          Image(s) to extract the largest connected component from.
          See :ref:`extracting_data`.
  
      Returns
      -------
      3D Niimg-like object or list of
          Image or list of images containing the largest connected component.
  
      Notes
      -----
      **Handling big-endian in given Nifti image**
      This function changes the existing byte-ordering information to new byte
      order, if the dtype in given Nifti image has non-native data type.
      This operation is done internally to avoid big-endian issues with
      scipy ndimage module.
