[Plugin: NextGEN Gallery] NextGen on static page?

Hi everybody,
I have a static HTML page. On that page I want to show the latest 10 posts from my WordPress Blog.
I managed to do that with this code:

<?php
require('./blog/wp-blog-header.php');
?>

<?php
$args = array( 'numberposts' => 10 );
$lastposts = get_posts( $args );
foreach($lastposts as $post) : setup_postdata($post); ?>
<?php echo get_the_post_thumbnail($post->ID, 'full'); ?>
	<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
	<?php the_content(); ?>
<?php endforeach; ?>

It works fine. The only thing is, that it does show the images as thumbnails. The same as on my WordPress Blog where I use the NextGen plugin.
I want to show the full image on my static page, because when I click on the image it directs me to another page for the large image and I don’t want that.
So my question is: is it possible to show the large image on the static page? Or is it possible to show the large image in a lightbox when I click on the thumbnail?
Thanks.
This is my testpage.

Johanna
