Making Sure a Thumbnail Shows Up on Facebook Share

Since my posts don’t have a “featured image” when they get auto-shared to Facebook there is no image next to the link. This is a bit annoying. I assume there is some simple solution but the two plugins I tried didn’t seem to have any settings for a default. They just used the featured image too. I found some code to add to the functions.php file to make it work for now but I’ll need to find a permanent solution.

Modifying the functions.php file also alerted me to the fact that I should probably be using child themes so I can apply updates to the themes I’m using without overwriting my changes.

Hopefully this works.
