[Plugin: NextGEN Gallery] Slideshow Uncaught Type Error

My attempts to use the slideshow feature are producing js function errors:

<script type="text/javascript" defer="defer">
jQuery(document).ready(function(){
jQuery("#ngg-slideshow-1-93-1").nggSlideshow( {id: 1,fx:"fade",width:320,height:240,domain: "https://www.tackypolice.com/",timeout:10000});
<strong>Uncaught TypeError: Object [object Object] has no method 'nggSlideshow'</strong>
});
</script></div>
