   I tried to use the snippet in the wordpress wiki to first check if there's a gravatar, and only if there isn't one I want user photo to display the user thumbail. But it's not working, because it's not showing the gravatar (only the fallback avatar like monsterid). I DO NOT want to override all the gravatars with the user photo, they should only be displayed if there's no gravatar.

   Can anyone help with this?!

   function validate_gravatar($email) {
   	$hash = md5($email);
   	$uri = 'http://www.gravatar.com/avatar/' . $hash . '?d=404';
   	$headers = @get_headers($uri);
   	if (!preg_match("|200|", $headers[0])) {
   		$has_valid_avatar = get_avatar($email, '80');
   	} else {
   		$has_valid_avatar = userphoto_the_author_thumbnail($author);
   	}
   	return $has_valid_avatar;
   }

   Trying to call the function:
   echo validate_gravatar(get_the_author_meta('user_email'));
