Media Library Categories

Question

I am using the following to assign categories to my WordPress Media Library (in functions.php):

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

Each Media Library item is assigned specific categories...I have some code that is returning the latest 5 images from the Media Library which looks like (in footer.php):

<?php
    $args = array(
        'post_type' => 'attachment',
        'post_mime_type' => 'image',
        'orderby' => 'post_date',
        'order' => 'desc',
        'posts_per_page' => '5',
        'post_status' => 'inherit'
    );
    query_posts($args);
?>
    <?php if ( have_posts() ) : ?>
        <div class="wrap">
            <h5><span>Recently</span> Added</h5>
            <ul>
                <?php
                    while ( have_posts() ) : the_post();
                    $url = get_attachment_link(get_post_thumbnail_id());
                    $image = wp_get_attachment_image_src(get_the_ID(), "thumbnail");
                ?>
                    <li><a href="<?php echo $url; ?>"><img src="<?php echo $image[0]; ?>"></a></li>
                <?php endwhile; ?>
            </ul>
        </div>
    <?php else : ?>
        <div class="wrap">
            <h5>Oops...</h5>
            <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
        </div>
    <?php endif; ?>
<?php wp_reset_query(); ?>

What I'd like to do is only return the images if they have an assigned category.

Any help is appreciated.

Thanks,

I found a solution!

My code changed quite a bit...

Here is what the functions.php file looks like (which did not change):

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

But here is the new code in footer.php, which returns the images from the Media Library, but only from an assigned category:

<?php
    $args = array(
        'post_type' => 'attachment',
        'numberposts' => '5',
        'category_name' => 'your-category-name'
    );
    $images = get_posts($args);
    if (!empty($images)) {
?>
    <div class="wrap">
        <h5><span>Recently</span> Added</h5>
        <ul>
            <?php
                foreach ($images as $image) {
                    $attachment_link = get_attachment_link( $image->ID );
                    echo "<li><a href='".$attachment_link."'>".wp_get_attachment_image($image->ID)."</a></li>";
                }
            ?>
        </ul>
    </div>
<?php } else { ?>
    <div class="wrap">
        <h5>Oops...</h5>
        <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
    </div>
<?php } ?>

I could have tweaked my existing code my adding category_name => 'your-category-name' to my $args, but this is a much more simplified approach and does the exact same thing...it just uses get_posts instead of query_posts.
