@bknightly i cant say how to use it with ID,
but i can show you how to use a size, when you do it with array (3 option beside id and url)
$items = wp_get_nav_menu_items('menu_name'); //replace menu_name with menu-name, menu-id, menu-slug (menu-location is not valid!)
foreach((array) $items as $key => $item) {
$taxonomy = $item->object;
$term_id = $item->object_id;
$url = $item->url;
$title = $item->title;
$image_url= get_field('icoon', $taxonomy._.$term_id); //replace "icoon" with the fieldname you give to the image
echo '<li><a href="'.$url.'" title="'.$title.'"><img src="'.$image_url[sizes][large].'" /></a></li>'; //replace large with size you wish
}
hope that help nevertheless
just if someone is interested, i use this for build a taxonomy menu with images:
<?php
get_header();
// to build a menu with image and name from a Taxonomy i use this (inside my archive-CPT.php):
//this values you need to adjust:
//my_taxonomy => slug of taxonomy (3x)
//my_taxonomy_image => name of imagefield at taxonomy page (1x)
//teaser_thumbnail => image size
$terms = get_terms("my_taxonomy", array(
'hide_empty' => 0
));
$count = count($terms);
if ( $count > 0 ){
foreach ( $terms as $term ) {
$permalink = get_term_link( $term->slug , 'my_taxonomy');
$output .= '<div class="taxonomy_menu_item"><a href='.$permalink.' titel="'.$term->name.'">';
$my_taxonomy_teaserimage = get_field('my_taxonomy_image', 'my_taxonomy_'.$term->term_id);
$size_taxonomy_teaserimage = 'teaser_thumbnail';
$taxonomy_teaserimage = $my_taxonomy_teaserimage['sizes'][ $size_taxonomy_teaserimage ];
$width_taxonomy_teaserimage = $my_taxonomy_teaserimage['sizes'][ $size_taxonomy_teaserimage . '-width' ];
$height_taxonomy_teaserimage = $my_taxonomy_teaserimage['sizes'][ $size_taxonomy_teaserimage . '-height' ];
$output .= '<img alt="'. $term->description .'" src="'. $taxonomy_teaserimage .'" width="'.$width_taxonomy_teaserimage.'" height="'.$height_taxonomy_teaserimage.'" />';
$output .= '<h3>'.$term->name.'</h3>';
$output .= '</a></div>';
}
}
echo $output;
get_footer();
?>
