Howdy. I'm using a plugin that generates a post thumbnail automatically when a post with a URL is submitted. It's called Video Thumbnails (http://sutherlandboswell.com/2010/11/wordpress-video-thumbnails/). It works on the backend but on my front-end form it doesn't. Do I need to call function or script when submit is clicked on the front-end in order for it to work properly? Thanks!
