facebook share/like/comment -> define thumbnail image

Published by guldi on Oktober 24th, 2011 in tipps, social media, facebook

Defining the thumbnail picture used by facebook on fb-commenting, liking or sharing web content:

Set some headertags:

<link rel="image_src" href="Your_URL_to_the_image'" />
<meta property="og:image" content="Your_URL_to_the_image" />

If you use drupal, you can use this snippet:

  $url = url($relative_img_path, array('absolute' => true));
  drupal_set_html_head('<link rel="image_src" href="' . $url . '" />');
  drupal_set_html_head('<meta property="og:image" content="' . $url . '" />');
