Cannot attach gallery on custom post types

There is no way to list “own” post types in pulldown on a gallery create page.

Changing your code in workbox_YV_video::get_galleries() to:

$args = array(
  'numberposts' => 100,
  'post_type' => array('custom_posttype1', 'custom_posttype2', 'post'),
  'orderby' => 'post_title', 'order' => 'DESC'
);
$posts = get_posts($args);

fixes the problem.

Can you provide a option to be able to configure “post_types”?
