Currently, it's impossible to control what image will be shown on Facebook when sharing the virtual festival catalogue page. Most of the time there's no image at all or something random. This is a big deal because not having this makes it much harder to share the festival catalogue professionally. We are having to embed it to be able to share it reasonably. I think this one should be top priority - so many festivals are using the Eventive platform to screen digital content and not being able to customize how it's shared is a problem. Maybe you can just incorporate an SEO plug-in?
