Here's what is going on. When I have a post with multiple thumbnails linking to the "medium-sized" image posts, there is no link back to the parent post. If someone gets to this page via a search engine, then they have no way of knowing that there is more related content.
Example:
Parent post
http://geek.thinkunique.org/2008/07/18/watchmen-trailer-1/
Sub post
http://geek.thinkunique.org/2008/07/18/watchmen-trailer-1/watchmen1/
Let me know if there is a way to add a link back to the parent post. Thanks in advance.
If you found out anything please let me know.
What I did was create a template called image.php which is basically the same as my index.php but where the entry would go I put the following code:
<p>This post belongs to <strong><a href="<?php echo get_permalink($post->post_parent); ?>" rev="attachment"><?php echo get_the_title($post->post_parent); ?></a></strong></p>
<p style="text-align:center" class="attachment"><a title="<?php the_title(); ?>" href="<?php echo wp_get_attachment_url($post->ID); ?>"><?php echo wp_get_attachment_image( $post->ID, 'medium' ); ?></a></p>
This puts a link back to the parent post and below that is the medium-sized image.
