I'm setting up a meta box with an image uploader following Alex's example at Theme Foundation: http://themefoundation.com/wordpress-meta-boxes-guide/
However, the upload button isn't working as nothing happens when clicking on the button.
I've checked the source code and I've noticed the .js file is missing. Please, may someone have a look to see what I'm doing wrong?
This is my functions.php file: http://snipt.org/zjmj8
And this is /js/meta-images.js file: http://snipt.org/zjnb3
