How do I make the tabs appear in K2 items for media and image gallery?
Like on the demo
demo.getk2.org/item

I only get this:
181.224.136.162/~lonepine/index.php?option=com_k2&view=item&layout=item&id=1&Itemid=274

This is new joomla install

This is all done with template overrides.

The tabs used are these jquerytools.github.io/

You can also download the template from here -> nuevvo.com/downloads/free-templates/item/86-takai
