Get Attachment Category Name

Question

How can I call the name of an attachment category?

Something that would look like <?php get_attachment_category_name ?> or $attachment->category_name

This would simply output the name of the category, which was created using the below function:

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

The answer was found here: http://www.wprecipes.com/how-to-display-category-name-without-link

For my purposes, I needed to define the category function and then call it by name-only inside the php echo:

     <?php
$category = get_the_category($attachment->ID);
    echo 'html goes here';
    echo ''.$category[0]->cat_name.';
    ?>

Additionally, to help eliminate space or punctuation in the category name, it can display the slug instead:

<?php
$category = get_the_category($attachment->ID);
    echo 'html goes here';
    echo ''.$category[0]->slug.';
    ?>
