need loop displaying single post from one category

Hey all
I’m designing a page that will display a single post from one category. These posts contain images and I want the loop on this page to display just one post but then have people be able to page through the rest of the posts with the post nav buttons. I am using:
<?php query_posts(‘cat=14&showposts=1’); ?>
and this works but the navigation buttons don’t work, it just keeps displaying the same post. What is the best way to do this?
This is the page in question:http://josephinesdream.com/?page_id=34
thanks
