Here is the specification of RSS feed :

If you do not add proper markup, obviously your RSS feed will fail to pass validation. More specifically :

Actually we were fixing an issue (automatically added “This articlet post name published first on The Customize Windows by Abhishek Ghosh. “) Later discovered that it was added by WP SEO. There was a request to write a guide on how to ddd Post Thumbnail in RSS Feed, so we looked a bit deeper on the topic. You need to add this snippet on your active Theme’s / Child Theme’s functions.php file :

---

function your_post_thumbnail_feeds($content) {
	global $post;
	if(has_post_thumbnail($post->ID)) {
		$content = $content . '<div><a href="' . the_permalink($post->ID) . '">' . get_the_post_thumbnail($post->ID) . '</a></div> ' . $content;
	}
	return $content;
}
add_filter('the_excerpt_rss', 'your_post_thumbnail_feeds');
add_filter('the_content_feed', 'your_post_thumbnail_feeds');

function your_post_thumbnail_feeds($content) {

global $post;

if(has_post_thumbnail($post->ID)) {

$content = $content . '<div><a href="' . the_permalink($post->ID) . '">' . get_the_post_thumbnail($post->ID) . '</a></div> ' . $content;

}

return $content;

}

add_filter('the_excerpt_rss', 'your_post_thumbnail_feeds');

add_filter('the_content_feed', 'your_post_thumbnail_feeds');

It will give you thumbnail on RSS plus the thumbnail will link back to the post. Please troubleshoot validation checking the standard. We have added / used div as none is using an uniform WordPress theme.

your is a just name; you can change to something of your choice. Well, here is lot of discussion on the topic :
