Images not displaying on the blog
You can add featured images to your blog posts by going into the individual post you’d like to edit and find the Featured Image section in the right-hand sidebar of your editor. Then insert the image you would like to show up on your blog page.
Then Update or Publish your post.
If you do not see the featured image option, select Screen Options in the top right-hand corner to open the menu, then check the box labeled Featured Image.
