   Hi all

   I've created a function to place a random thumbnail image on a page of a client's website. The function looks like:

   function inspired_by_image ($size='thumbnail')
   {
   	$attachments =& get_children(array('post_parent' => get_the_ID(), 'post_type' => 'attachment', 'post_mime_type' => 'image', 'orderby' => 'rand'));
   	if (!empty($attachments)) {
   		$first_attachment = array_shift($attachments);
   	}
   
   	echo wp_get_attachment_image($first_attachment->ID, $size);
   
   }

   It's working fine, excerpt for that the client would like to add an _external_ link to the image, as opposed to linking to the image itself - e.g. the image links to http://www.google.com.

   I noticed the Link URL field in the image uploader section ignores manually typed in links that are not on the site. Do i need to create a separate field in the database to pull this off?

   A simple workaround to this is to add the link to the description field.

   yes,
   that's exactly with what I ended up.
   Only a workaround because the URL field is not made for optional links.
