First of all, thank you for developing this plugin and spending the time to reply to the support forum. That means a lot.
I'll get right down to it:
Can events have featured images?
I am developing a shortcode to work hand in hand with your plugin to display the 4 closed events complete with featured image.
I know that I could crawl the post for the first occurrence of an image and display that,(also considered using custom fields) but that's just one heck of a hack.
Let me know and thanks again!
