How to Add Post Thumbnail to your WordPress RSS Feeds

In this article, we will show you how you can add post thumbnails to your WordPress RSS feeds with a simple function. The sad truth is that even if you enable the post thumbnails, it will not show up in your RSS feeds. In our earlier tutorial, we showed you how you can add post thumbnails in WordPress. But we have a solution for that.

All you have to do is open your theme’s functions.php file and add the following code:

function rss_post_thumbnail($content) {
global $post;
if(has_post_thumbnail($post->ID)) {
$content = '<p>' . get_the_post_thumbnail($post->ID) .
'</p>' . get_the_content();
}
return $content;
}
add_filter('the_excerpt_rss', 'rss_post_thumbnail');
add_filter('the_content_feed', 'rss_post_thumbnail');

Feel free to style this however you like. Remember to activate WordPress post thumbnails using our main WordPress post thumbnail tutorial before adding it to your RSS.
