Hi

thanks for your replay!
Let me remain you just that we are using Nextgen Gallery plus.

Yes theme is using Redux framework.

There is one file in theme folder called class-hybrid-media-grabber.php
here is source code of it:

<?php
/**
 * Hybrid Media Grabber - A script for grabbing media related to a post.
 *
 * Hybrid Media Grabber is a script for pulling media either from the post content or attached to the
 * post.  It's an attempt to consolidate the various methods that users have used over the years to
 * embed media into their posts.  This script was written so that theme developers could grab that
 * media and use it in interesting ways within their themes.  For example, a theme could get a video
 * and display it on archive pages alongside the post excerpt or pull it out of the content to display
 * it above the post on single post views.

If post type is marked as galley then specific template file is called which contain code

<?php if ( $gallery = hybrid_media_grabber( array( 'type' => 'gallery', 'split_media' => true ) ) ): ?>
	<div class="meta-media"><?php echo $gallery; ?></div>
<?php endif; ?>

Thanks for helping!

Hi @greenshady
I’m glade to hear that this will be implemented for next-gen 🙂
Till then could you please give me a quick fix for my solution? 🙂

Thanks for helping 🙂

yes of course.

Nextgen gallery use shortcodes
you can read here
