Lightbox clone not working after update Twenty Twelve Theme

Hi all,

Trying to narrow down what has happened as recently updated WordPress from 3.5.2 to 3.6 and also the Twenty Twelve theme from 1.1 to 1.2.

I have a child theme with a few minor modifications, one of which was a Lightbox clone called fancybox. I used the tutorial to implement fancybox for Twenty Twelve taken from here WPTUTS here

https://wp.tutsplus.com/tutorials/theme-development/add-a-responsive-lightbox-to-your-wordpress-theme/

I have removed the Twenty Twelve update and the issue still persists, now wondering if this is caused by the 3.6 WordPress update?

My website and a page that contains images that previously worked can be seen here https://coder-tronics.com/microcontroller-gpio-protection/

My child Functions.php only contains the following code related to Fancybox, so not sure what the issue is at this stage?

/*********************----------
* LIGHTBOX CLONE CODE SECTION
----------*********************/

/* SCRIPTS AND STYLES FOR FANCYBOX ---------------------------------------- Add acripts and styles for Fancybox */
function twentytwelve_add_lightbox() {
    wp_enqueue_script( 'fancybox', get_template_directory_uri() . '/inc/lightbox/js/jquery.fancybox.pack.js', array( 'jquery' ), false, true );
    wp_enqueue_script( 'lightbox', get_template_directory_uri() . '/inc/lightbox/js/lightbox.js', array( 'fancybox' ), false, true );
    wp_enqueue_style( 'lightbox-style', get_template_directory_uri() . '/inc/lightbox/css/jquery.fancybox.css' );
}
add_action( 'wp_enqueue_scripts', 'twentytwelve_add_lightbox' );

Any help would really be appeciated,

Cheers,

Ant
