   Hey,

   I am trying to get the posts id within the rss feed so i can display the posts thumbnail as i am using press75.com "Simple Post Thumbnails" plugin and how you would get the thumbnail normally from within a post would be like:

   get_thumbnail($post->ID);

   I have inserted the following code into my functions.php file to display an image within the rss:

   function feedFilter($query) {
   	if ($query->is_feed) {
   		add_filter('the_content', 'feedContentFilter');
   		}
   	return $query;
   }
   add_filter('pre_get_posts','feedFilter');
   
   function feedContentFilter($content) {
   	$thumbId = get_post_thumbnail_id();
   
   	if($thumbId) {
   		$img = wp_get_attachment_image_src($thumbId);
   		$image = '<img align="left" src="'. $img[0] .'" alt="" width="'. $img[1] .'" height="'. $img[2] .'" />';
   		echo $image;
   	}
   
   	return $content;
   }

   This will place a thumbnail next to the text within the rss feed.

   So to display my thumbnail from my currant plugin i would have to retrieve the posts id as this line of code does:

   $img = wp_get_attachment_image_src($thumbId);

   but i am using the custom plugin so i would need to use something like:

   $img = get_thumbnail($post->ID);

   the only thing is $post->ID wont work outside the loop so my question is does anyone know how i can achieve this type of operation outside the loop?
