I’d love to add a caption to my feature image on blog posts. Do you have an update coming soon that might allow for this?

To resolve this issue, you can add the following code to the functions.php file:

function the_post_thumbnail_caption() {
 global $post;

 $thumbnail_id    = get_post_thumbnail_id($post->ID);
 $thumbnail_image = get_posts(array('p' => $thumbnail_id, 'post_type' => 'attachment'));

  if ($thumbnail_image && isset($thumbnail_image[0])) {
   return '<div class="front-caption">'.$thumbnail_image[0]->post_excerpt.'</div>';
  } else {
    return;
  }
}

Then open the content-sigle.php file, find and replace the following code:

<?php if( has_post_thumbnail() ) : ?>
    <div class="entry-thumbnail"><?php the_post_thumbnail(); ?>

With new code:

    <?php if( has_post_thumbnail() ) : ?>
    <div class="entry-thumbnail"><?php the_post_thumbnail(); ?>
<p class="caption"><?php echo the_post_thumbnail_caption(); ?>

Hope this helps !
