Linking image to page

Hello people,

I just installed the NextGen Gallery plugin. I would like to link the images in my gallery to another page. I already installed “NGG Custom Fields” and added a link in the custom field to try it out. I read that I have to change this:

<div class="ngg-gallery-thumbnail" >
<a href="<?php echo $image->imageURL ?>"
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>
		</div>

In my nggallery.php-file to this:

<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>

If you need more information to solve this please tell me!
