I have followed the plural site tutorial for creating a new plugin, in this case a slide show like the nivo one.  After tweaking this for 3.8, The admin section appears to work fine, i can create a slideshow and upload pictures for the slides.

I assign this to a widget zone (this case homepage top) i enable the slide widget in the widgets settings tab.  I clear cache and refresh the homepage, but no slider is shown.

The plugin is installed, there are no errors i can see, widget is enabled, slide show is created, isactive, is bound to a widget zone and has slides.

source code  is my plugin, can anyone see why my slideshow isnt showing at all?
