Displaying Categorised Media items

Hi Folks,

I’ve added some code to my functions.php file to allow me to categorise my media library:

function wptp_add_categories_to_attachments() {
    register_taxonomy_for_object_type( 'category', 'attachment' );
}
add_action( 'init' , 'wptp_add_categories_to_attachments' );

How do I display a lists of the items within a certain category within my theme – I’ve tried the standard method of listing posts but this doesn’t work.

Thanks Darren
