Overlay images not available for displaying

From semantic-mediawiki.org

I tested on Opera 12.15 for Win/Linux and the images overlay option stops working on this wiki. It was fine a few days ago.

I just checked Overlay images with Opera 12.02 and it works.

Due to the language issue, the JS script needed a change therefore pages served by the ResourceLoader need to be purged.
