        // Width of star image in case the plugin can't work it out. This can happen if
        // 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
