Alt and Title Tag on Images

I’m using this code to display the taxonomy images associated with a post which outputs the image HTML without any ALT or Title tags.

<?php
print apply_filters( 'taxonomy-images-list-the-terms', '', array(
    'after'        => '</ul>',
    'after_image'  => '</li>',
    'before'       => '<ul class="taxonomy-images-the-terms">',
    'before_image' => '<li>',
    'image_size'   => 'detail',
    'taxonomy'     => 'feature',
    ) );
            ?>

Any advice on how to get the image HTML to use the taxonomy name for ALT and Title tags?

Thanks.
