  I am using the gallery field to display a gallery. No trouble with getting all the images into html.

  For the layout, it would be neccessary to assign different classes to the images: portrait and landscape. And to render differnt sizes. Say, I have one thumb-size for portrait and one for landscape.

  For the wp only solution, I ve been using this little snippet:

  <?php
  
    $post_thumbnail_id = get_post_thumbnail_id( $post_id );
    $imgmeta = wp_get_attachment_metadata( $post_thumbnail_id );
    
    if ($imgmeta['width'] > $imgmeta['height']) {
      the_post_thumbnail('large', array('class' => 'landscape'));
    } else {
      the_post_thumbnail('medium', array('class' => 'portrait'));
  }
  
  ?>

  See what I am aming for?

  I am sure, it can be done with the gallery filed as well. Unfortunately I am not sure where to start..

  Thanks for help and thoughts

  Cheers
