How to get category image custom post type taxonomy in wordpress?

From the details page of the WPCustom Category Image Plug-in : https://wordpress.org/support/plugin/wpcustom-category-image

1st – Go to Wp-Admin -> Posts(or post type) -> Categories (or taxonomy) to see Custom Category Image options.

2nd …depending on whether you want to show a single category image or display several in a loop –

//SINGLE

echo do_shortcode('[wp_custom_image_category onlysrc="https://wordpress.org/plugins/wpcustom-category-image/false" size="full" term_id="123" alt="alt :)"]');

//LOOP

foreach( get_categories(['hide_empty' => false]) as $category) {
    echo $category->name . '<br>';
    echo do_shortcode(sprintf('[wp_custom_image_category term_id="%s"]',$category->term_id));
}

In addition there is an example category template here –
