Да.

И все же, какая функция ответственна за отображение галереи? Она работает на div'ах (очень криво), я бы хотел переделать все в таблицу... где искать?

ok, thx.
/modules/image/contrib/image_gallery

[.........

function theme_image_gallery($galleries, $images) {
drupal_set_html_head(theme('stylesheet_import', base_path() . drupal_get_path('module', 'image_gallery') .'/image_gallery.css'));

// We'll add height to keep thumbnails lined up.
$size = _image_get_dimensions('thumbnail');
$width = $size['width'];
$height = $size['height'];

$content = '';
if (count($galleries)) {
$content.= '

';
foreach ($galleries as $gallery) {
$content .= '
• ';
  if ($gallery->count)
  $content.= l(image_display($gallery->latest, 'thumbnail'), 'image/tid/'.$gallery->tid, array(), NULL, NULL, FALSE, TRUE);
  $content.= "
  

  ".l($gallery->name, 'image/tid/'.$gallery->tid) . "

  \n";
  $content.= '

  }
  $content.= "

}
$content.= "

\n";

if (count($images)) {
$height += 75;
$content.= '

if ($pager = theme('pager', NULL, variable_get('image_images_per_page', 6), 0)) {

Да вроде все заработало, как хотелось.
