Hi @projectarthouse,
Thanks for the post.
Your loading script looks correct, the issue might be arising from how you are getting the ACF data. Have you been able to debug your variables to check if the expected image data is being returned?
To debug, you would need something like this:
<?php
$image = get_field('image_field_name');
echo '<pre>';
var_dump( $image );
echo '</pre>';
?>
