Code

protected function convertUrlToAbsolute($url) {

  // Convert paths relative to the hostname, that start with a slash, to
  // ones that are relative to the Drupal root path; ignore protocol-relative
  // URLs.
  if (strpos($url, base_path()) === 0 && strpos($url, '//') !== 0) {

    // Logic:
    // * Get the length of the base_path(),
    // * Get a portion of the image's path starting from the position equal
    //   to the base_path()'s length; this will result in a path relative
    //   to the Drupal installation's base directory.
    $len = strlen(base_path());
    $url = substr($url, $len);
  }

  // Pass everything else through file_create_url(). The alternative is to
  // use url() but it would insert '?q=' into the path.
  return file_create_url($url);
