Hi, it’s me again i found a solution for my problem and i wanted to share it :

I decided to assign an album to a user using a new table :

CREATE TABLE wp_user_album(
	id INT PRIMARY KEY,
	user_id INT NOT NULL,
	album_id INT NOT NULL,
	FOREIGN KEY (user_id) REFERENCES WP_USERS(ID)ON DELETE CASCADE,
	FOREIGN KEY (album_id) REFERENCES wp_ngg_album(id)ON DELETE CASCADE
);

The assignation will be done manually on phpmyadmin for instance.

Then i created a function which i hooked on the action ‘ngg_created_new_gallery’ which is right after the creation of a new gallery. You can drop this at the bottom of the admin/functions.php :

/**
* Add a gallery automatically in the user's album (set manually in the table wp_user_album)
* @param: $galleryid Id of the gallery created
* Hooked to the action 'ngg_created_new_gallery', return nothing
*/
add_action('ngg_created_new_gallery', 'add_gallery_to_user_album', $galleryid);
function add_gallery_to_user_album($galleryid){

	global $wpdb;

	//Get the gallery
	$gallery = nggdb::find_gallery($galleryid);

	//Get the user id
	$user_id = $gallery->author;

	//Get the album of the user
	$user_album = $wpdb->get_row($wpdb->prepare("SELECT * from {$wpdb->prefix}user_album where user_id = %d", $user_id), ARRAY_A);
	$album = nggdb::find_album($user_album['album_id']);

	//If the user has an album
	if($album != null){

		//Create an array with the new gallery id
		$new = array($gallery->gid);

		//Merge it with the array of existing galeries id
		if(count($album->gallery_ids) > 0)
			$sort = array_merge((array)$album->gallery_ids, $new);
		else
			$sort = $new;

		//serialize it
		$serialized = serialize($sort);

		//Update the album
		$wpdb->query("UPDATE $wpdb->nggalbum SET sortorder = '$serialized' WHERE id = $album->id ");
	}

	//BEGIN DEBUG
	$debug = '[author : '.$gallery->author.'] [album id : '.$album->id.'] [serialized : '.$serialized.']';
	nggGallery::show_message($debug);
	//END DEBUG

}

Therefore, every time a user with an assigned album will create a gallery it will be automatically added to its album and displayed on the page with the album shortcode (eg : [album id=1 template=compact]).

Hope it will help,
