You can also fix it by updating the settings to use the class hook:

s = jQuery.extend({
        ...
        hook: "rel",
        animation_speed: "fast",
        ajaxcallback: function() {},
        slideshow: 5e3,
        autoplay_slideshow: false,
        opacity: .8,
        ...

to:

s = jQuery.extend({
        ...
        hook: "class",
        ...
