Animation settings HTML Content

Using the following code I'm displaying Drupal messages through Lightbox:

  <?php if ($show_messages && $messages): ?>
  <div id="lightboxAutoModal" style="display: none;" ><?php print $messages; ?></div>
  <?php endif; ?>

However the animation is nice for Photos or other media, but for notification messages is quit distracting and inefficient. Would it be possible to have a checkbox in admin settings to turn off animation for HTML Content?

Kind regards,

Marius
