thx mate, your love helps me a lot.
your code modified include the permalink at the image:
<?php $values = get_post_custom_values("image"); // set the img custom name
if (isset($values[0])) { // if there's a img in my custom field
?>
<a>" rel="bookmark" title="<?php the_title_attribute(); ?>"><img src="<?php $values = get_post_custom_values("image"); echo $values[0]; ?>" title="<?php the_title(); ?>"/></a>
<?php } // end if statement
// if there's no img do replace it with no-img
else { ?>
<a>" rel="bookmark" title="Read the rest of <?php the_title_attribute(); ?>"><img src="<?php bloginfo('stylesheet_directory'); ?>/images/no-img.gif" title="<?php the_title(); ?>"/></a>
<?php } ?>
