Image Metadata in WordPress

WordPress saves some meta data of the uploaded images, as far as it is possible to extract them. I will show you how to display this infos right under the picture.

All we need is one function in functions.php:

function myMetaData($pic) {
  $html = '';
  $meta = wp_get_attachment_metadata($pic);
  if($meta) {
      $html = '<ul>';
      foreach($meta['image_meta'] as $key => $value) {
          $html .= '<li>' . $key . ': <strong>' . $value . '</strong></li>';
      }
      $html .= '</ul>';
  }
  return $html;
}

<?php  echo myMetaData($post->ID); ?>

This is how it looks in the default theme::
