Can I add something like "rel=$post_id" to post thumbnail? (2 posts)

    I need to add a rel attribute(which is equal to post id) to every post thumbnail image. It can be done by simple preg_replace, but that will reside in the function.php file. I can not think of a way to retrieve the subjected post id from there. However, I must need the post id in the attribute.
    I actually want the output like this:
    <img src="#something" rel="#i_need_the_post_id_here"/>
    Any clue on this?

    try this:
    <img src="#something" rel="#<?php echo $post->ID; ?>"/>
