Lightbox Error


I just added lightbox according to the Codex guide and adjusted the JS call as per the recommendation of John on version 2.51 here

However, before and after I updated the call, I was getting this error on my public items show page:

Fatal error: Call to undefined function item_has_thumbnail() ....default/items/show.php

Is there a reason why this would happen with a fresh install of Lightbox?

That sounds like you using Omeka 2.x, but Lightbox hasn't been updated for for the Omeka 2.x series. It is uncertain that it will be at this point.

Ok. Do you know if there is a similar lightbox solution that might work with Omeka 2.x?
