Facebook Shared Image

A shared image is one of the most common forms of sharing on Facebook. These images will always appear on your timeline, and ideally they will show up in most of your followers’ News Feeds — though with the Facebook algorithm determining which content will be served, it’s unlikely that everyone will see your post. The more people engage with your post, the more likely it is that the rest of your followers and their followers will see that activity.
