How can I add a class if category has parent

Hi I love your plugin!

I have got it doing what I want, except how to add a class to categories that are parent categories. Or a class for child categories.

This is what I have so far.. please ignore the bad formatting…

This code shows all my categories in hierarchal order:

<?php
$terms = apply_filters( 'taxonomy-images-get-terms', '', array(
	'taxonomy' => 'category',
		'term_args'    => array(
			'orderby'      => 'id',
			'order'        => 'ASC',
			'hierarchical' => 1,
		),
	) );
if ( ! empty( $terms ) ) {

	foreach( (array) $terms as $term ) {
		print "\n" . '<div class="postbox" id=" ' . esc_html( $term->name ) . ' ">';
		print "\n\t" . '<h1 style=" margin-top: 10px; " class="entry-title"><a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '">' . esc_html( $term->name ) . '</a></h1>';
		print "\n\t" . '<div class="entry-meta"><span class="entry-date">There are ' . esc_html( $term->count ) . ' posts in this category</span></div>';
		print "\n\t" . '<div class="home-thumb"><a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '">' . wp_get_attachment_image( $term->image_id, 'home-thumb' ) . '</a></div>';		

		print "\n\t" . '<div style="margin: 0px 0 0 0; z-index: 99999; position: relative; height: 50px; overflow: hidden; padding: 0 10px">' . esc_html( $term->description ) . '</div>';
		print "\n" . '<div class="readmore" style="position: relative; height: 52px; display: block; padding: 10px 0;"><a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '"> View All ' . esc_html( $term->name ) . '</a></div>

                ';
		print "\n" . '<div class="clearfix"></div></div>';

	}
}
?>

It is this line

print "\n" . '<div class="postbox" id=" ' . esc_html( $term->name ) . ' ">';

that I would like to add the class ‘parent’ to if it is one.`

Hope to hear from you, or anyone else who can help!
