Create and register new template and use from do_shortcode function

Hi, I’ve create this template based on defaults:

<?php if (!defined('ABSPATH')) die('No direct access allowed'); ?>
<?php if (!empty($gallery)) { ?>
    <ul class="grid effect-8" id="grid">
        <?php foreach ($images as $image) : ?>
            <li>
                <img title="<?php echo $image->alttext ?>" alt="<?php echo $image->alttext ?>" src="<?php echo $image->thumbnailURL ?>" <?php echo $image->size ?> class="img-responsive" />
                <div class="post-icon">
                    <a href="<?php echo $image->imageURL ?>" title="<?php echo $image->description ?>" rel="prettyPhoto2"><span class="icon-zoom-in"></span></a>
                </div>
            </li>
            <?php if ($image->hidden) continue; ?>
        <?php endforeach; ?>
    </ul>
<?php } ?>

and I called the file gallery-masonry.php and save the file in /wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/view/. After that in my template I’m using shortcode as follow: <?php echo do_shortcode('[ngg_images source="recent" display_type="photocrati-nextgen_basic_masonry"]'); ?>
but doesn’t work, why I’m doing wrong?
