Bring images to on the fly social shares on comparison page

[katska]

When social sharing from They Vote For You, (where cards are not pre-rendered) such as on a page that has at least one picture, no picture is not shown for Facebook or twitter, which makes the shared snippet less eye-catching. Would be great to have an image come through with the text and bring a bit of life to on these social shares.

Strangely its inconsistent, because I found an image appears for PMs in Facebook.
