How do I purge Image Cache in ZenPhoto 1.4.5?

Question

In the previous version of Zenphoto I had installed, there was a big button on the overview page 'Purge Image Cache'. This has now gone.

I need this facility. Does anyone know where it is now located.

Answer 1

I found you need to Enable the cacheManagerplugin.

I don't remember having to do this before, maybe its off by default now.
