    //Add metaboxes to Sector taxonomy ///////////////////////////////////////////////////////

add_filter( 'rwmb_meta_boxes', 'prefix_register_taxonomy_meta_boxes' );
function prefix_register_taxonomy_meta_boxes( $meta_boxes ){
    $meta_boxes[] = array(
        'title'      => 'Extra info',
        'taxonomies' => 'base_sector', // List of taxonomies. Array or string

        'fields' => array(
        // featured image
          array(
                'name' => 'Featured Image',
                'id'   => 'tax_img',
                'type' => 'image_advanced',
            ),
        ),
    );
    return $meta_boxes;
}

    In my template I'm trying to output the image but can't figure out how to do it.

    <?php // Get Sectors
			$post_type = 'base_project';
			// Get all the taxonomies for this post type
			$taxonomies = get_object_taxonomies( array( 'post_type' => $post_type ) );

			foreach( $taxonomies as $taxonomy ) :
			 // Gets every term in this taxonomy
				$terms = get_terms( $taxonomy );
					foreach( $terms as $term ) :

	  			 echo "<div class='grid-item'><div class='pic sector'>";

	$images = get_term_meta( $term->term_id, 'image_advanced', false );

	if ( $tax_images ) {
	    foreach ( $tax_images as $tax_image ) {
    $tax_image = RWMB_Image_Field::file_info( $tax_image, 'thumbnail' );

   		echo "<img src='{$tax_image['url']}' alt='{$tax_image['alt']}' />";
	    }
	}

?>

    taking from the example in the documentation

    // Getting images
$image_ids = get_term_meta( $term_id, $field_id, false ); // Media fields are always multiple.
foreach ( $image_ids as $image_id ) {
    $image = RWMB_Image_Field::file_info( $image_id, array( 'size' => 'thumbnail' ) );
    echo '<img src="' . $image['url'] . '">';
}

    I've setup the metaboxes like this

    add_filter( 'rwmb_meta_boxes', 'prefix_register_taxonomy_meta_boxes' );
function prefix_register_taxonomy_meta_boxes( $meta_boxes ){
    $meta_boxes[] = array(
        'title'      => 'Extra info',
        'taxonomies' => 'base_sector', // List of taxonomies. Array or string

        'fields' => array(
        // featured image
          array(
                'name' => 'Featured Image',
                'id'   => 'tax_img',
                'type' => 'image_advanced',
            ),
        ),
    );
    return $meta_boxes;
}

    I've been playing around with it for hours and can't get it to work.

    Hi there,
    Can you use var_dump( $image_ids ) and give me the output?

    Thanks.

    Managed to sort it. I wasn't query the terms properly.

    <?php $custom_terms = get_terms('base_sector');

	  foreach($custom_terms as $custom_term) {

	  	$term_id = $custom_term->term_id;

				$image_ids = get_term_meta( $term_id, 'tax_img', false );
					foreach ( $image_ids as $image_id ) {
					    $image = RWMB_Image_Field::file_info( $image_id, array( 'size' => 'thumbnail' ) );
					    echo "<img src='{$image['url']}' alt='{$image['alt']}' />";
					}

				}

?>
