Simply paste the following code in your functions.php file. The post thumbnail should be visible once you saved the file.
function diw_post_thumbnail_feeds($content) { global $post; if(has_post_thumbnail($post->ID)) { $content = '<div>' . get_the_post_thumbnail($post->ID) . '</div>' . $content; } return $content; } add_filter('the_excerpt_rss', 'diw_post_thumbnail_feeds'); add_filter('the_content_feed', 'diw_post_thumbnail_feeds');
