Hi,

How do I display the cloneable single image fields in the frontend?
This is the code of the custom field:
```
array (
                'id' => 'fotos',
                'type' => 'single_image',
                'name' => 'Foto\'s',
                'force_delete' => 1,
                'clone' => 1,
                'max_clone' => 3,
                'add_button' => 'Nog een foto',
            ),
```
How to refer to the individual fields?
[rwmb_meta meta_key="fotos???" link="true" size="thumbnail"]

To add here: I guess it would be better to display the images as a gallery, so that the images are all nicely displayed, also if e.g. the 2nd image would be deleted.

How to disply the images as a gallery?

Hi,

Yes, you can display images as a gallery. Please try this code:
```
$images = rwmb_meta( 'fotos', ['size' => 'thumbnail'] );
echo '<div class="gallery">';
foreach ( $images as $image ) {
    echo "<a href='{$image['full_url']}'><img src='{$image['url'}'></a>";
}
echo '</div>';
```

Anh,

When I add this code to XYZ PHP Code Snippet, the webpage stops loading.
What am I doing wrong?

Which PHP version are you using? I’m writing in PHP 5.4 (that accepts short array syntax). Please upgrade if you’re using lower PHP version.

Can you turn on debug and see what the error is? My code is created in my mind without testing, so it might have some conflict.
