How to Display Thumbnails in a List From a Specific Category

Are you looking for a way to display thumbnails from the “featured image” field in the post editor? While there’s probably a plugin for this, we have created a quick code snippet that you can use display thumbnails in a list from a specific category in WordPress.

Instructions:

All you have to do is add this code to your theme’s single.php file:

<?php

  $thumbnails = get_posts('numberposts=6&cat=3');
  foreach ($thumbnails as $thumbnail) {
    if ( has_post_thumbnail($thumbnail->ID)) {
	echo '<li class="s-uppdrag-margin">';
	echo '<a href="' . get_permalink( $thumbnail->ID ) . '" title="' . esc_attr( $thumbnail->post_title ) . '">';
	echo get_the_post_thumbnail($thumbnail->ID, 'thumbnail');
	echo '</a>';
	echo '</li>';
    }
  }

?>

You need to replace your post ID and category ID in the above code to display the list of thumbnails.
