Custom Field Image Listing

Thank you very much, the restet code worked beautifully!

I have a new problem now.

The thumbnail listing should go on the right hand side of every page. It lists all the thumbnails of every post correctly on the homepage, but if I goto a posts page it only show the thumbnail for that post.

My code is as follows.

<?php if (have_posts()) : ?>
  <?php while (have_posts()) : the_post(); ?>
    <?php if(get_post_meta($post->ID, "small-image", true)) : ?>
      <a href="<?php the_permalink(); ?>" class="thumbnail"><img src="<?php echo get_post_meta($post->ID, "small-image", true); ?>" /></a>
    <?php endif; ?>
  <?php endwhile; ?>
<?php endif; ?>

I assume that have_posts is looking on the current page, and not going to the root of the site to look for posts.

Thanks again,

(bit belated, sorry)

What code can I use for global posts? So that it will show ALL posts regardless of what page your on?

Thanks!
