I have major troubles with your plugin causing a 500 internal server error on the frontend and backend. It happened a week after I installed it. I manually had to delete the plugin, reinstall it, and all was fine for a day, then the error happened again. In chrome, it says "SERVER ERROR – the website encountered an error while retrieving http://www.jeffcoffin.com - It may be down for maintenance or configured incorrectly. // HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request."
I narrowed it down to the TWIG folder inside of the VENDOR folder. Is it a necessary extension? I'm using your plugin on the most basic settings (only to rotate images when a page reloads). I'd be delighted to find out if I didn't need it, because its a great plugin. I host with Media Temple (quoted from their php settings panel: Congratulations, all your domains are using the current stable version of PHP on (gs) (currently 5.3.15) by default.). This is a one-click install of the latest version of WordPress (3.4.2).

Thanks for your time
