When I publish a post, I click “Share” to post it on Facebook. It used to allow me to write a post with a link to my blog. And there was a thumbnail with an image from my post. Sometimes it was the wrong image (from another post), but there were little arrows that allowed me to choose the image that I wanted to appear on Facebook with the post and the link. And there was a checkbox that said “No thumbnail”. Now there are NO choices – the image that is shown is NOT from the post that I am trying to share and there isn’t even an option of “No thumbnail”.
