Your module would look something like this:
[code]
//get the info
if ($my->id != 0) {
        $user_id = $my->id;
} else {
        $user_id = '';
}
//parameters
$database->setQuery("SELECT * FROM #__gallery2");
$param = $database->loadRowList();

/* extract params from the DB query */
$MOS_GALLERY2_PARAMS = array();
foreach ($param as $curr) {
    $MOS_GALLERY2_PARAMS[$curr[0]] = $curr[1];
}
	if (! defined("MOS_GALLERY2_PARAMS_PATH")) {
        define ("MOS_GALLERY2_PARAMS_PATH",$MOS_GALLERY2_PARAMS['path']);
    }
    if (! defined("MOS_GALLERY2_PARAMS_RELATIVEG2PATH")) {
        define ("MOS_GALLERY2_PARAMS_RELATIVEG2PATH",$MOS_GALLERY2_PARAMS['relativeG2Path']);
    }
    if (! defined("MOS_GALLERY2_PARAMS_EMBEDURI")) {
        define ("MOS_GALLERY2_PARAMS_EMBEDURI",$MOS_GALLERY2_PARAMS['embedUri']);
    }
    if (! defined("MOS_GALLERY2_PARAMS_EMBEDPATH")) {
        define ("MOS_GALLERY2_PARAMS_EMBEDPATH",$MOS_GALLERY2_PARAMS['embedPath']);
    }
    if (! defined("MOS_GALLERY2_PARAMS_LOGINREDIRECT")) {
        define ("MOS_GALLERY2_PARAMS_LOGINREDIRECT",$MOS_GALLERY2_PARAMS['loginredirect']);
    }

$start_id = 'null';
$max_depth = 'null';
//here we go
$ret = GalleryEmbed::init(array(
           'embedUri' => MOS_GALLERY2_PARAMS_EMBEDURI,
           'embedPath' => MOS_GALLERY2_PARAMS_EMBEDPATH,
           'relativeG2Path' => MOS_GALLERY2_PARAMS_RELATIVEG2PATH,
           'loginRedirect' => MOS_GALLERY2_PARAMS_LOGINREDIRECT,
           'activeUserId' => $user_id,
		   'fullInit' => true,
		   'activeLanguage' => $lang));
		   
list ($ret, $tree) = GalleryCoreApi::fetchAlbumTree($start_id, $max_depth);
	    if ($ret->isError()) {
		if ($ret->getErrorCode() & ERROR_PERMISSION_DENIED) {
		    $tree = null;
		} else {
		    return array($ret->wrap(__FILE__, __LINE__), null);
		}
		}//end error
		list ($ret, $items) = GalleryCoreApi::loadEntitiesById(GalleryUtilities::arrayKeysRecursive($tree));
	    if ($ret->isError()) {
		return array($ret->wrap(__FILE__, __LINE__), null);
	    }
	    foreach ($items as $item) {
		$title = $item->getTitle() ? $item->getTitle() : $item->getPathComponent();
		$titles[$item->getId()] = preg_replace('/\r\n/', ' ', $title);
		//print "$title";
		$itemId = $item->getId();
		print '<a href="'.MOS_GALLERY2_PARAMS_EMBEDURI.'&g2_view=core.ShowItem&g2_itemId='.$itemId.'">'.$title.'</a><br />';   
		}
GalleryEmbed::done();
[/code]
this is rough code and doesn't give depth of the album!!
