How to change Open Graph tags when form link is shared via Facebook

When published, is it possible to put an image in the block that begins 

I want to show an image in Facebook, GooglePlus, and, I hope, our website. I have test published it and the form returns data. I'd just like it to look better.

The information you see in Facebook is based on the Open Graph meta tags. Unfortunately, we do not provide an option to edit those tags. I have forwarded a ticket to our developers to see if this situation can be improved at some point.

Note, if you add the link to the Facebook Page, the Facebook will allow you to add the image and edit the text.

We will let you know if we have any updates on the ticket.
