If you share a page on your favourite social media you should hopefully now get an image with it too, since Voice sets the appropriate information into the page source.
I've been testing it out on the Voice Twitter Page. Do try it with your own pages and let us know how you get on!

Now that images have been added to Events in the Events Calendar app, if you share an event to Twitter/Facebook/etc the image and description will be used.
