I got it to work.
I had to add the wp load php.
<?php
require_once('./blog/wp-load.php');
define('WP_USE_THEMES', false);
?>
Then I added in the Dynamic Content Gallery widget javascript to the top of my page. I got the javascript from the working wp page that had the widget working on it.
This info could help to try to get other plugins going outside of wp.
See what I did here:
