Ben,
Great question. I took a look and I believe a couple of edits to the custom-js.php file will take care of that for you. Take out this section:
// Load Lightbox and add lightbox class and rel for prev/next functionality
jQuery(document).ready(function(){
jQuery('.lightbox').lightbox();
jQuery('.gallery a').addClass('lightbox');
jQuery('.gallery a').attr('rel', 'gallery');
});
and also this:
// superfish
jQuery(document).ready(function(){
jQuery('#nav-bar ul').superfish({
delay: 1000,
animation: {opacity:'show',height:'show'},
speed: 'fast'
});
});
Save your changes and see if that won’t do it for you. That will remove the call for the lightbox and also the superfish drop-down script from loading in the footer.
If you run into any questions or trouble, let me know,
Bill
