Did you know that we’re only three people here at Nelio? And, yet, our posts are pretty cool, huh? That’s because of our new plugin, Nelio Content! Do you want to use it too? At the end of 2009 WordPress 2.9 was released. One of the most interesting features it included was featured images—a new tool themes could enable to improve the look and feel of our blog.
Assuming you’re already using them in your own blog (it’s 2017, so why shouldn’t you?), you’ve probably realized that you may only use images in the media library as featured images. However, if you add a regular image in your posts, you can do so using their URL and, therefore, you can skip the media library. Why so?
Today I’ll explain how featured images work in WordPress, why you can only use images from your media library, and how Nelio Content overcomes this limitation and allows you to set featured images using an external URL.
Featured Images in WordPress
As you can see in WordPress.com:
A featured image represent the contents, mood, or theme of a post or page. Posts and pages can have a single featured image, which many themes and tools can use to enhance the presentation of your site.
