How to count media attachments?

How do I count the number of media attachments a specific post has?

Output example: This post has 22 photos.

Thanks!

Use this code if you’re in the loop:

$attachments = get_children( array( 'post_parent' => $post->ID ) );
$count = count( $attachments );

If you’re not in the loop, substitute $post->ID with the ID of the specific post. But that should count all attachments.
