Render thumbnail

[cornelyus]

Hi,
Thanks for the plugin..

It's working great, but I was in the need to also print the thumbnail of the post.
Was looking for how to do this, and found this code for using on our theme functions.php

function rss_post_thumbnail($content) {
global $post;
if(has_post_thumbnail($post->ID)) {
$content = '<p>' . get_the_post_thumbnail($post->ID) .
'</p>' . get_the_content();
}
return $content;
}
add_filter('the_excerpt_rss', 'rss_post_thumbnail');
add_filter('the_content_feed', 'rss_post_thumbnail');

It works for the "general" feed of the website, but for the popular posts feed the thumbnail image is rendered always the same one, from the last published post.

I believe that it concerns the line "global $post;" line that gets the latest post, not the other being used on the loop..

Have any suggestion how could it also render the post thumbnail?
