   Hi I use the following function to add a thumbnail to the post in the rss feed.

   <?php
   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');
   ?>

   But instead of only using the post_thumbnail that I have to set mannualy I would like the function to fallback to the first uploaded image of the post's gallery (thumbnail size).

   How can I do this ?

   Many thanks for your time and help.
