next/previous post navigation

Hi,

first thing to say is that I have a very little knowledge in php/css, but I guess what I want to do isn’t difficult. Each post on my blog is an image. I want to do image/post navigation similar to facebook ( when you press on left side of photo you go to previous and on the right side – next)

I’ve found this code

<?php previous_post('« « %', '', 'yes'); ?>
| <?php next_post('% » » ', '', 'yes'); ?>

when I add it to single.php file I get links to previous and next image, but I can’t figure it out how to move them on top of the image.
