Module has fatal PHP error!

I wanted to explore this module. I still don't know if it's what I need but it was missing a little code. I got this error [10-Sep-2009 09:39:52] PHP Fatal error: Call to undefined function _image_gallery_parent_select() in /home/thechefs/public_html/sites/all/modules/gallery_manage/gallery_manage.module on line 165 so I googled _image_gallery_parent_select and found the function at http://api.lullabot.com/_image_gallery_parent_select. I figured that I should just cut and paste into the module, saved it, upload it and it seems to work.

I'm going to have a look at the module and see if it works now. I'll get back to you on it.

Here is the code to put in the module.

 function _image_gallery_parent_select($tid, $title) {
  $parents = taxonomy_get_parents($tid);
  if ($parents) {
    $parent = array_shift($parents);
    $parent = $parent->tid;
  }
  else {
    $parent = 0;
  }

  $children = taxonomy_get_tree(_image_gallery_get_vid(), $tid);

  // A term can't be the child of itself, nor of its children.
  foreach ($children as $child) {
    $exclude[] = $child->tid;
  }
  $exclude[] = $tid;

  $tree = taxonomy_get_tree(_image_gallery_get_vid());
  $options[0] = '<'. t('root') .'>';
  if ($tree) {
    foreach ($tree as $term) {
      if (!in_array($term->tid, $exclude)) {
        $options[$term->tid] = str_repeat(' -- ', $term->depth) .' '. $term->name;
      }
    }
  }

  return array(
    '#type' => 'select',
    '#title' => $title,
    '#default_value' => $parent,
    '#options' => $options,
    '#description' => t('Image galleries may be nested below other galleries.'),
    '#required' => TRUE
  );
}
