Doesnt seem to work for me.

ZC 1.3.8

Lightbox 1.5

Renamed the following to match my Template:
includes\languages\english\extra_definitions\YOUR-TEMPLATE-FOLDER
includes\modules\YOUR-TEMPLATE-FOLDER
includes\templates\YOUR-TEMPLATE-FOLDER

Ran SQL command
No error, 4 proesssed message above
LightBox is under my Config / Zen LightBox in ZC

However, when I can on any of my images, it opens in the "normal" ZC popup box.
