The featured image function in WordPress is great. Because so many themes take advantage of it these days, you are missing an opportunity to spruce up your site if you don’t take advantage of it as well.
The problem is that sometimes it’s easy to forget to upload the featured image. This is especially true for many clients or site users who have publishing permission. It’s also one more thing for them to learn and have to remember.
The Auto Featured Image plugin makes this problem go away. It automatically inserts the first image from your post into your featured image spot.
It also has the ability to do this for posts that were published before the plugin was installed. You will just need to go to the settings page for the plugin and click the one and only button. (Settings > Auto Featured Image)
