First, let me say thank you for creating Fresco. All the other lightbox plugins I've tried fall flat when it comes to being truly responsive on smaller screens, but Fresco works beautifully.
This issue I'm running into has to do with Youtube and Vimeo videos. It appears the user has the choice of providing their own cover image or settle for a not very attractive grey box that says "Click to Play!" This is a new one on me, as everyplace that I've ever embedded videos (forums, facebook, wordpress, etc..) automatically displays the preview from youtube. Is there a way to do the same with Fresco, preferably automatically?
A few details: I'm using the Fresco Wordpress plugin from https://github.com/chrismccoy/fresco
on a wordpress site. I did purchase a single site license, downloaded the Pro version, and overwrote the JS and CSS from the plugin, which didn't seem to break anything. And it's for a multisite in which many of the sub-site admins may be technically challenged. Thus, I want everything to be as automated as possible.
Any advice is greatly appreciated. Thanks!
