I'm using Taxonomy Images, and I can't figure out how to display a category's associated image on a single.php. Essentailly, when a user is viewing a post that utilizes the single.php template, it should display the post's category's image. Right now, it just doesn't display anything.

This is the code that I'm using:

<?php 




    $image_id = apply_filters( "taxonomy-images-queried-term-image-id", 0 );




    if ( ! empty( $image_id )):




    print apply_filters( "taxonomy-images-queried-term-image", "",  array(




        "image_size" => "large"




    ) );




    endif;




?>
