Gallery Title Cache issue

Hi I am using this plugin.
I am displaying 6 galleries on one page. But on hover of 1st image of any gallery I need to display the TITLE of gallery.

when i changed code to display title in file
plugins/nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/view/gallery.php

below
<?php if (!defined ('ABSPATH')) die ('No direct access allowed'); ?><?php if (!empty ($gallery)) : ?>
like this
<p class="gallery-title" style="display:none;"><?php echo $gallery->title ?></p>
It does not even display title in firebug. but when clear cache from backend it displays and gallery images are being hide.
so when i remove code and clear cache than it shows images back.

What i Need to do. Please suggest me ASAP.
