I just installed Simple Image Gallery Pro and it made the thumbnails just fine. However it doesn't seem to matter which method I use for a popup, there is a problem with all of them.

URL in question: pioneer-school.org/index.php?option=com_content&task=view&id=99&Itemid=80

Now my template uses litebox-1.0.js, moo.fx.js, prototype.lite.js

If I use thickbox or grey box, it simply opens a new browser window with the pix. If I use slimbox, nothing happens and firebug reports an error in mootools.js
If I use lytebox it opens the pix offset to the right, the spinner keeps spinning and I get no navigation buttons.
If I use lite box, the top half of the browser turns grey and a white box opens up for a photo, but no photo appears and no navigation. I also have found various layering issues with the menu bar as I have tried various methods, but I have attributed that to z-index, which I am sure that I can fix.

I currently have it set for greybox so it doesn't look too stupid.
I have turned the Joomla cache off and it doesn't effect it. I am stumped.

JCE Utils Mambot unpublished and both Litebox and Lytebox perform the same, popup to blank white square with only the upper half of the area having a dark gray background with no navigation icons. I guess the good news is that Firebug reports no javascript errors.
