Custom Taxonomy Image on front-end

i created a custom-post-type called “products” which has a custom-taxonomy called “department”.

in that taxonomy is an ‘add image’ metabox set up for users to add an image to represent the department on the front-end.

can you help me get it to display the front-end? i can’t seem to make it happen.

they should show on this page: https://staging10.thestudio-patrick.com/products/

here is my page-products.php code:

<div class="row">					
<?php
	$terms = get_terms('department'); 
		foreach ( $terms as $term ) {
			echo '<div class="col-sm-12 col-md-3">';

				echo '<a href="/department/' . $term->slug . '">' . $term->name . '</a>';

				echo '<div style="border:1px solid blue;">';
					//$file = wp_get_attachment_image( get_post_meta( get_the_ID(), '_cmb2_term_dept_img_id', 1 ), '' );
					$file = get_post_meta( $post->ID, '_cmb2_term_dept_img', true );
					echo $file;
				echo '</div>';

				echo '<div style="border:1px solid yellow;">';
					$file = get_post_meta( get_the_ID(), '_cmb2_term_dept_img', true );
					//$file = wp_get_attachment_image( get_post_meta( get_the_ID(), '_cmb2_term_dept_img_id', 1 ), '' );
					foreach ( (array) $file as $attachment_id => $attachment_url ) {
						echo '<div id="gallery" class="gallery gallery-size-thumbnail">';
							echo '<figure class="gallery-item">';
								echo '<div class="gallery-icon landscape">';
									echo '<a rel="prettyPhoto[pp_gal]" href=" ';
										echo $attachment_url;
										echo '">';
										echo wp_get_attachment_image( $attachment_id );
									echo '</a>';
								echo '</div>';
							echo '</figure>';
						echo '</div>';
					}	
				echo '</div>'; // closes yellow border div

			echo "</div>";// closes .col-sm-12 and .col-md-3 div
	}	
?>
</div><!-- eof: .row -->

and here is my code from my metabox-functions file:

<?php
/**

    // Add other metaboxes as needed

}

really hoping someone can point me in the right direction
