We have several posts on our blog which start with a video, e.g.:
However, when people post the link to such a post on their facebook page, no image is displayed in facebook even though a starting image/preview picture (for the still modus) has been defined in vimeo — c.f. post “Frachter zeigt Flagge…” from 16 August on this facebook page: https://www.facebook.com/superpeng.
What can we do to make sure an image is displayed on facebook when people post a link to a blog post (we want to keep the video right at the top of our post, though)?
Many thanks for your help!
