Taxonomy Images parameters

Is it possible to get it to display the children of a parent term?
Here is the code i’m using.

<?php
$terms = apply_filters( 'taxonomy-images-get-terms', '', array(

    'taxonomy'     => 'mycustomtaxonomy',
    'parent' => $termID,

    ) );

if ( ! empty( $terms ) ) {

    foreach( (array) $terms as $term ) {

        $termlink=esc_url( get_term_link( $term, $term->taxonomy ) );

        echo '<a href="' . $termlink . '">' . wp_get_attachment_image( $term->image_id, 'gallery-thumb' ) . '</a>';

        //echo $term->description;

    }

}
?>
