I have a CPT, where I have added a Taxonomy Advanced field with the id "art_author". The field is connected to the taxonomy "author".

For this taxonomy I have added a custom Image Advanced field with the id "tax_image". So for each term I can add an author image.

In the template for the CPT (actually a Bricks Builder template) I can easily get the author name using:
$terms = rwmb_meta( 'art_author' );

But how do I get the author image(s) in the CPT template? When I test with your suggested code:
```
// Displaying uploaded images:
$images = rwmb_meta( 'tax_image', [ 'object_type' => 'term', 'size' => 'thumbnail' ], get_queried_object_id() );
?>
<h3>Uploaded images</h3>
<ul>
	<?php foreach ( $images as $image ) : ?>
		<li><img src="<?= $image['url']; ?>"></li>
	<?php endforeach ?>
</ul>
```
I just get the error message:
Warning: foreach() argument must be of type array|object, string given ...

What do I miss?

Hello,

If you use this code get_queried_object_id() in the CPT template, it will return the current post ID, not the term ID. So you need to pass the term ID to the helper function rwmb_meta().

If the option multiple is not set for the field, you can use the variable $terms to pass to the third parameter. For example:
```
$terms = rwmb_meta( 'art_author' );
$images = rwmb_meta( 'tax_image', [ 'object_type' => 'term', 'size' => 'thumbnail' ], $terms );
```
Please read more in the documentation https://docs.metabox.io/fields/taxonomy-advanced/#data
https://docs.metabox.io/extensions/mb-term-meta/#data

Thanks!

If I change to
$images = rwmb_meta( 'tax_image', [ 'object_type' => 'term', 'size' => 'thumbnail' ], $terms );
it still does not produce anything (and no error message). If I do print_r($images); it prints "1".

Hello,

Can you please print out the variable $terms to see what value it is stored?

print_r($terms) gives only the standard WP content of the "author" taxonomy:
```
    [0] => WP_Term Object
        (
            [term_id] => 15
            [name] => John Doe
            [slug] => john-doe
            [term_group] => 0
            [term_taxonomy_id] => 15
            [taxonomy] => author
            [description] => Teacher
            [parent] => 0
            [count] => 0
            [filter] => raw
            [term_order] => 1
        )
)
```
Where is my MB custom field "tax_image" connected to my taxonomy "author"?

Hello,

It's an array of term objects so you need to use a loop to get each term ID. In this case, you can use the sample code to get the author images:
```
$images = rwmb_meta( 'tax_image', [ 'object_type' => 'term', 'size' => 'thumbnail' ], $terms[0]->term_id );
```
