%url/%pics using the wrong variable...

Hi guys,

In the following function, I changed the '%pics' entries from $value to $content['value'] which I think would do better. What do you think?

function nodewords_extra_pics_prepare(&$tags, $content, $options) {
  if (!empty($content['value'])) {
    if ($options['type'] == NODEWORDS_TYPE_NODE) {
      $tags['pics-label'] = strtr(
        '(pics-1.1 "http://www.icra.org/pics/vocabularyv03/" l gen true for %url r (%pics))',
        array(
          '%url' => nodewords_url("node/{$options['id']}"),
          '%pics' => $content['value'],
        )
      );
    }
    elseif ($options['type'] == NODEWORDS_TYPE_PAGE) {
      $tags['pics-label'] = strtr(
        '(pics-1.1 "http://www.icra.org/pics/vocabularyv03/" l gen true for %url r (%pics))',
        array(
          '%url' => nodewords_url($_GET['q']),
          '%pics' => $content['value'],
        )
      );
    }
  }

  if (variable_get('nodewords_icra_validation_content', '')) {
    $tags['pics-label:meta'] = nodewords_url('labels.rdf', array('absolute' => TRUE));
  }
}
