JQuery :: How To Implement Page Curl Effect On Storefront

I'm relatively new to jquery, and I'm attempting to implement a "Page Curl" effect (by Elliot Kember) on my BigCommerce storefront. Here is the plugin: [URL].
Here is my storefront: [URL]

I've got the jquery referenced in my HTMLHead.html page, and my scripts are all uploaded to my folder "/turn" on my site. However, I can't seem to find the right page for placement of my 'call function':
$(document).ready(function(){
$( '#target' ).fold();
});
And the 'element';
<img id="target" src="turn/code.png">

Am I placing these on the correct pages for a proper 'call' of the scripts? There are numerous pages referenced that make-up the HTMLHead.html page, and I'm finding a hard time trying to place the jquery plugin on the right pages.
