I don't know how to write code, I just have a simple wordpress website and blog. So any technical answers wont help. I can cut and paste the occasional code if I know where to put it. I am a total non geek.
When I post my blog posts on Facebook one of two ads from my widget area shows up as thumbnail choices. I have nice photos on my blog posts.
I plugged in a few plug in suggested here, but nothing happened.
