nextGEN custom fields + jj ngg jquery slideshow

Pessoal,
Estou com dificuldade em colocar link nas imagens do slideshow. a ideia é fazer um slideshow de noticias destaque, linkando a imagen a determinado post.

segui esse tutorial para utilizar custom fields e estou utilizando o jj nextgen slideshow jquery para transicao de imagens.

porem altero a pagina view/gallery.php e aparece somente a transicao de imagens sem linkar.

link do site.

codigo view/gallery.php

<!-- Thumbnails -->
        <?php foreach ( $images as $image ) : ?>

        <div id="ngg-image-<?php echo $image->pid ?>" class="ngg-gallery-thumbnail-box" <?php echo $image->style ?> >
                <div class="ngg-gallery-thumbnail" >
                        <a href="<?php echo $image->ngg_custom_fields["link"]; ?>" title="<?php echo $image->description ?>" <?php echo $image->thumbcode ?> >

                                <img title="<?php echo $image->alttext ?>" alt="<?php echo $image->alttext ?>" src="<?php echo $image->thumbnailURL ?>" <?php echo $image->size ?> />
                        </a>
                        <a href="<?php echo $image->ngg_custom_fields["link"]; ?>">
                        <?php echo $image->alttext ?>
                </div>
        </div>

        <?php if ( $image->hidden ) continue; ?>
        <?php if ( $gallery->columns > 0 && ++$i % $gallery->columns == 0 ) { ?>
                <br style="clear: both" />
        <?php } ?>

        <?php endforeach; ?>
