So i found this method to get the thumbnail with the rss feed, using this code, at the end of functions.php theme file
// THIS INCLUDES THE THUMBNAIL IN OUR RSS FEED
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');
From this thread

Problem is that when i use it, the thumbnail gets in the description node of the rss feed, and i get the full html code for the image, not just the url.
So it looks something like this
<description><img src=blabla/>textfromthepost</description>
How can i get only the url of the thumbnail, and put it inside its own node like <thumb></thumb>?
