Can't delete

Thanks for an excellent module - the way it handles images is really neat.

I've noticed what looks like a bug in the permissions. A user with "delete any node image" permission can not delete images which were added by someone else. I think it's a simple typo in function _node_images_access. Here's my suggested fix - hope it's useful.

/**
 * Check access to add, edit or delete node images.
 */
function _node_images_access($op, $node, $file = NULL) {
  global $user;

  $type = node_get_types('type', $node);
  if (!isset($type->type)) return FALSE;

  $type = strtolower($type->type);
  if ($op == 'create') {
    return (user_access('add node images to any '. $type .' content') || (user_access('add node images to own '. $type .' content') && ($user->uid == $node->uid)));
  }
  if ($op == 'update') {
    // changed "node_image" to "node image"
    return (user_access('edit any node image') || (user_access('edit own node images') && ($user->uid == $file->uid)));
  }
  if ($op == 'delete') {
    // changed "node_image" to "node image"
    return (user_access('delete any node image') || (user_access('delete own node images') && ($user->uid == $file->uid)));
  }

  return FALSE;
}
