That’s just what I needed. Nice!

Ok I found the solution. It seems that manage_posts_custom_column gets called while rendering *all* post type objects including posts, pages, and custom post types.

Therefore to fix the repeating problem simply check for the post type before getting the terms.

case "artist":
if ($post->post_type == 'gallery') {
    $terms = wp_get_post_terms($post->ID, 'artist');
    echo $terms[0]->name;
}
break;

Thanks to shibashake.com for the info, in particular this post:

Just a follow up to my question.

I ended using custom post types and custom permalinks to organise the site structure.

A helpful blog post on using a taxonomy in your permalink structure can be found here

@wmmead:

You need to include the ‘post_parent’ as an argument so it only looks at the current post.

Here’s the full function I’m using: (a combo of AGWD101 and danielwiener code)

function the_post_thumbnail_caption() {
  global $post;

  $thumb_id = get_post_thumbnail_id($post->id);

  $args = array(
	'post_type' => 'attachment',
	'post_status' => null,
	'post_parent' => $post->ID,
	'include'  => $thumb_id
	); 

   $thumbnail_image = get_posts($args);

   if ($thumbnail_image && isset($thumbnail_image[0])) {
     //show thumbnail title
     echo $thumbnail_image[0]->post_title; 

     //Uncomment to show the thumbnail caption
     //echo $thumbnail_image[0]->post_excerpt; 

     //Uncomment to show the thumbnail description
     //echo $thumbnail_image[0]->post_content; 

     //Uncomment to show the thumbnail alt field
     //$alt = get_post_meta($thumbnail_id, '_wp_attachment_image_alt', true);
     //if(count($alt)) echo $alt;
  }
}
