label_outlinechat_bubble_outline Comment

Have you ever wanted to add featured images to your WordPress RSS feed? Many times your RSS feed will only show images that you’ve put into the post, but it won’t show featured images. There’s a quick and easy fix that will remedy this problem.

Add the below code to your functions.php file within your theme folder:

function insertThumbnailRSS($content) {
global $post;
if ( has_post_thumbnail( $post->ID ) ){
$content = '' . get_the_post_thumbnail( $post->ID, 'thumbnail' ) . '' . $content;
return $content;

add_filter('the_excerpt_rss', 'insertThumbnailRSS');
add_filter('the_content_feed', 'insertThumbnailRSS');

If you’d like to change the size of the thumbnails simply replace the word “thumbnail” in ( $post->ID, ‘thumbnail’ ) with either “medium”, “large” or “full”.

Now refresh your blog url and see the results. We hoped you liked this tutorial on adding featured images to your WordPress RSS Feed.
