   I'm using NGG 1.8.3 over WP 3.2.1 Multisite.

   I'm calling two galleries directly from the templates with this lines:

   echo do_shortcode('[nggallery id=1]');
   echo do_shortcode('[nggallery id=2]');

   And I'm using a custom NGG template, located in a folder called /nggallery/ inside the theme folder. The customized gallery.php file looks like this:

   <?php if (!defined ('ABSPATH')) die ('No direct access allowed'); ?><?php if (!empty ($gallery)) : ?>
   
   	<?php
   	$total_imagenes = sizeof($images);
   	for ( $i=1; $i<=$total_imagenes; $i++ ) {
   		if ( !$images[$i]->hidden ) {
   			echo '<a href="' . $images[$i]->imageURL . '" title="' . $images[$i]->description . '" rel="shadowbox[' . $gallery->anchor . ']" ';
   			if ($i==1) echo 'id="fotosStart" ';
   			echo '></a>';
   		}
   		if ( $images[$i]->hidden ) continue;
   	}
   	?>
   
   <?php endif; ?>

   Gallery ID 2 works perfectly fine; the weirdness is related to gallery ID 1. It generates the HTML for all the images, but it won't pull the image URL, title or description from $images.

   Any ideas?

   (of course, thanks in advance for any help you may provide)

   I figured it out, so here is the answer in case of any of you should be looking to solve a similar issue.

   <?php
   if (!defined ('ABSPATH')) die ('No direct access allowed');
   
   if (!empty ($gallery)) :
   
   	$firstImage = true;
   	foreach ($images as $image) {
   		if ( !$image->hidden ) {
   			echo '<a href="' . $image->imageURL . '" title="' . $image->description . '" rel="shadowbox[' . $gallery->anchor . ']" ';
   			if ($firstImage) {
   				echo 'id="fotosStart" ';
   				$firstImage = false;
   			}
   			echo '></a>';
   		}
   		if ( $image->hidden ) continue;
   	}
   
   endif;
   ?>

   Apparently, it's better to use foreach to go through arrays.
