How do I set up a default thumbnail for my Facebook blogposts?
If you want a thumbnail to be displayed along with your post when automatically displaying it on your Facebook page, you need to add the "rsb_fb" class in the tag of the image that you have chosen as a thumbnail. The end result should look like this:
<img src="https://cdn.rsjoomla.com/path/to/image.jpg" class="rsb_fb" alt="test">
