Featured images, still referred as post thumbnails, are well-known WordPress feature which is supported by the vast majority of themes.
They serve as the primary image for your blog posts and are frequently displayed next to the heading on your home page and social media. All popular WordPress themes include support for featured images by default.
We will show you how to conveniently bring featured images or post thumbnails to WordPress in this article.
WordPress Featured Images for Beginners
Featured images are a feature of the WordPress theme. Almost all WordPress themes include built-in support for featured images, that are presented exquisitely across various areas of your WordPress website.
Visual elements are more appealing to us as humans than plain text. Featured images assist you in making your blog pages more visually appealing.
They also aid in increasing user engagement and page views. These images may also be used by search engines and social media websites and displayed in search results and social media news feeds.
Featured images are typically used for blog posts, but you can also use them for pages and custom post types.
Please keep in mind that featured images are not the same as cover images.
Having said that, let’s look at how to easily add featured images in WordPress.
Using WordPress to Add a Post Thumbnail or Featured Image
Simply edit or create a new blog post to add a featured image to a WordPress post.
The featured image tab is located in the right column of the content editor.
Clicking on the ‘Set Featured Image’ area will bring up the WordPress media uploader popup.
You can upload an image from your computer or use an existing image from your media library from this page. Simply click the Set Featured Image button after you’ve selected the image.
In the right column, WordPress will now display a preview of the featured image. However, depending on your WordPress theme, the actual featured image will look different.
You can still save or publish the post as well as preview it to see how your featured image would then look on your website.
The featured image appears with your posts automatically, based on the settings defined by your theme developer.
How to Locate and Use Featured Images Effectively
The next big question that most newbies have is where to find images to use as featured images.

- Negative Space – A well-organized collection of free images with no copyright.
- New Old Stock – An assortment of vintage photographs from public archives.

add_image_size( 'single-post-thumbnail', 590, 180 );

WordPress Featured Image Frequently Asked Questions
When using featured images on your blog as a beginner, you may encounter questions or issues. Some of the most frequently asked questions about featured images are listed below.
1. Why does the featured image reoccur in my posts?
Beginners frequently add a featured image before inserting the same image into the post editor’s content section.
Replace the image from the content area and just use the featured image metabox to add the featured image. For more information, see our article on how to fix a featured image that appears twice in WordPress.

Cover images are used in the body of your posts or pages. They are typically used to divide sections of a lengthy page or post.
The featured image is the image that represents an article. It appears before or alongside the content, but not within the article itself.
