Wordpress display custom taxonomy image on single post - php - php

Question

I´m trying to display a custom taxonomy image in the frontend on a single post.
Following situation:
Created a CPT for "Weine"
Added a taxonomy "winzer"
Added the following code to my functions.php to display the "winemaker" taxonomy with its description in the single post using a shortcode:
function wpb_catlist_desc() {
$string = '<div>';
$catlist = get_terms( 'winzer' );
if ( ! empty( $catlist ) ) {
foreach ( $catlist as $key => $item ) {
$string .= '<div>'. $item->name . '<br />';
$string .= '<em>'. $item->description . '</em></div>';
}
}
$string .= '</div>';
return $string;
}
add_shortcode('wpb_categories', 'wpb_catlist_desc');
Added an Image fieled to the "winzer" taxonomy using ACF. --> Here´s where I´m stuck now.
I need to add another line to the php snippet to also display the image using the shortcode.
Any hints how to get this done? :)
Cheers!!!!

function wpb_catlist_desc() {
$string = '<div>';
$catlist = get_terms( 'winzer' );
if ( ! empty( $catlist ) ) {
foreach ( $catlist as $key => $item ) {

Here's how I got it solved:
function wpb_catlist_desc() {
global $post;
$string = '<div>';
$catlist = wp_get_post_terms($post->ID, 'winzer');
if ( ! empty( $catlist ) ) {
foreach ($catlist as $item ) {
$image = get_field('winzer_bild', 'winzer_'.$item->term_id);
if(!empty($image)) {
$imgurl = $image['url'];
}
$string .= '<div>';
$string .= '<img class="winzer-bild-klein" src="' . $imgurl . '" alt="' . $item->name . '"style="width:100%;"/>';
$string .= '<h3 class="winzer-name-n">'. $item->name . '</h3>';
$string .= '<p>'. $item->description . '</p></div>';
}
}
$string .= '</div>';
return $string;
}
add_shortcode('wpb_categories', 'wpb_catlist_desc');
