   Hello,

   I have been using a theme that didn't support thumbnails on the home pages for over three years. I now have a massive amount of content without thumbnail posts.

   I want to switch to a theme that does support thumbnails. Is there a way to automatically generate thumbnails for all of my wordpress posts based on the first image in any given post to accomplish this? I really like some of the modern looks of these types of themes but it would be impossible to go back and custom field thumbnails one-by-one.

   If anyone knows of a solution for this, I would really appreciate it?

   Thank you!

   Try:

   <?php
   $args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_status' => null, 'post_parent' => $post->ID );
   $attachments = get_posts($args);
   if ($attachments) {
   	$thumb = $attachments[0];
   	echo wp_get_attachment_image( $thumb->ID, 'thumbnail' );
   }
   ?>
