You are most welcome. Glad it is working. Marking the topic as resolved.

Hi Piotr,
The comments are handled by activity and currently counting comments for gallery is not very efficient(and that’s why comment counts are not included).

If you still need it, I will post the code but please do know that it is not efficient and not very scalable solution. It will be nice to keep a count in one of the metas in future and sync them.

Hi Jon,
By RC, I meant Release candidate of the plugin.

You may try it on a test server.

Yes, the autologin will work.

Hope that clarifies.

Hi Paul,
Here is a completely working code that you can use. It is tested to work.

function add_member_images() {
	//Include image.php for helper functions
	require_once ABSPATH . 'wp-admin/includes/image.php';

	$title        = 'Nature is great';
	$content      = 'checking this out';
	$gallery_id   = 292; //change
	$media_type   = 'photo';
	$type         = 'image/jpeg';
	$url          = 'http://localhost/4.4.2/wordpress/wp-content/uploads/15-beach-sea-photography.jpg';
	$file         = '/wp-content/uploads/15-beach-sea-photography.jpg';
	$status       = 'public';
	$component_id = 1;
	$component    = 'members';

	$media_data = array(
		'title'          => $title,
		'description'    => $content,
		'gallery_id'     => $gallery_id,
		'user_id'        => get_current_user_id(),
		'is_remote'      => false,
		'type'           => $media_type,
		'mime_type'      => $type,
		'src'            => $file,
		'url'            => $url,
		'status'         => $status,
		'comment_status' => 'open',
		'storage_method' => mpp_get_storage_method(),
		'component_id'   => $component_id,
		'component'      => $component,
		//'context' => $context,
		'is_orphan'      => 0,
	);

	$id = mpp_add_media( $media_data );
}

add_action('mpp_actions', 'add_member_images');

Please update the fields as you need. It was giving fatal error because we did not include image.php which has some required functions needed for processing media.

Hope that helps.
