nested image galleries and overridding image_gallery.tpl.php

This module seems to break overriding the image gallery template. This would be necessary, in my case, where I have nested image galleries. I still want to format the "index" of galleries. Also, the flash seems to load even though there is no actual gallery - again in this case where there are nested galleries. It's probably easier to just point you to my site so you can see what I mean:
http://www.lisalightltd.com/portfolio/domestic

This "page" is what I am refering to as an index:

1) The simpleviewer is loading below evn though there are no images to display. I have it set to transparent so it can't be seen.

2) I want to override the format of these "blocks" in image_gallery.tpl.php according to this page:
http://drupal.org/node/41257
But it has no effect. Effects were apparent at /image viewing the galleries in the usual way. (I took down the override so don't look there now.)

Any advice on either issue?
