Get current post featured image ID

Question

Is it possible to retreive the current post (inside the loop) featured image ID?

The reason why I want this is so I can do something like this...

<?php

$featuredID = //get the featured image id

echo do_shortcode('[gallery size="thumbnail" link="file" exclude="' . $featuredID . '"]');  

?>

Any help would be great thanks!

Sounds like you're looking for get_post_thumbnail_id():

$featuredID = get_post_thumbnail_id();

It returns null if there's not a featured image, so you may want to add a check for that.
