    // the jQuery.dimensions plugin is not available OR the image is hidden at installation
    starWidth: 16 //,

    //NB.: These don't need to be pre-defined (can be undefined/null) so let's save some code!
    //half:     false,         // just a shortcut to control.split = 2
    //required: false,         // disables the 'cancel' button so user can only select one of the specified values
    //readOnly: false,         // disable rating plugin interaction/ values cannot be changed
    //focus:    function(){},  // executed when stars are focused
    //blur:     function(){},  // executed when stars are focused
    //callback: function(){},  // executed when a star is clicked
  }; //} });

  /*--------------------------------------------------------*/

		### Default implementation ###

		The plugin will attach itself to file inputs

		with the class 'multi' when the page loads

	*/

  //   $('input[type=radio].star').rating();
