Link to first and last page without a plugin

Hi,

Thanks in advance for any advise.

I created a new query to show 12 latest posts of category 1. Code below.

<code>
<?php
$page = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts("cat=1&showposts=12&paged=$page");
?>

<?php if(have_posts()) : ?><?php while(have_posts()) : the_post(); ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php endwhile; ?><?php endif; ?>

<?php posts_nav_link('','','Previous Posts') ?>

<?php posts_nav_link('','Recent Posts ','') ?>

</code>

This works perfectly including the links that shows the next or previous set of 12 posts but what I need to add is a couple of links that links to the first and last set of 12 posts.

I’m aware of the wp-pagenavi plugin of Lester Chan, but it does not fit to what I need to accomplish since I don’t need to show any page numbers in between the first and last links.

Cheers!
