Image gallery per user - dirty hack

I want all images uploaded by a user stored in a personal gallery.

Since i didn't find a suitable solution, i added a gallery for every user (username = gallery name) and changed the taxonomy module:

function taxonomy_form($vid, $value = 0, $help = NULL, $name = 'taxonomy') {
  $vocabulary = taxonomy_get_vocabulary($vid);
  $help = ($help) ? $help : $vocabulary->help;
  if ($vocabulary->required) {
    $blank = 0;
  }
  else {
    $blank = '<'. t('none') .'>';
  }
 
  //custom
  global $user;
  if ($user->uid!=1 && $vid==3) {                           //3 = image gallery Vocabulary ID(vid)
    $res = db_query('SELECT * FROM {term_data} WHERE name = "%s"', $user->name);
    $term_data = db_fetch_object($res);
           
    return array('#type' => 'select',
      '#title' => $title,
      '#default_value' => $value,
      '#options' => array($term_data->tid => $user->name),
      '#description' => $description,
      '#multiple' => $multiple,
      '#size' => $multiple ? min(9, count($options)) : 0,
      '#weight' => -15,
      '#theme' => 'taxonomy_term_select',
            );
  }
  //custom
 
  return _taxonomy_term_select(check_plain($vocabulary->name), $name, $value, $vid, $help, intval($vocabulary->multiple), $blank);
}

This causes only the gallery with the same name as current user is beeing showed to all users except admin for image upload.

Then i added a profile field where i entered a link to the gallery, so every user got his own gallery ;-)

Just wanted to know whether there is a better solution, which doesn't make things more complicated for my users.
