[Plugin: Slideshow Gallery] Thumbnails MIA….

Thumbnails aren’t showing up – help!

I don’t have any options in the plugin I installed. All I have available to me is Manage slides (name, description, URL of image, option for link…that’s it) and the Configuration menu. But that’s all… no where to turn on/off thumbnails….. I feel like I’m missing something!

Thank you!
