Thanks for this info! Also, in reply to an above question, you could restrict it based on category using the WP conditional:

<?php
if ( in_category( ‘your_category’ )) {
YOUR CODE
}
?>

So, for example:

<?php
if ( in_category( 'your_category' )) {
    $args = array(
        'post_type' => 'attachment',
        'numberposts' => null,
        'post_status' => null,
        'post_parent' => $post->ID
    );
    $attachments = get_posts($args);
    if ($attachments) {
        foreach ($attachments as $attachment) {
            echo wp_get_attachment_image($attachment->ID, 'medium');
        }
    }
}
?>
