Cornerstone - two images in one custom element not possible?

This is puzzling me - I added a second image control which woks in cornerstone as expected. But If I try to output it, instead of recieving the url the src shows just (unknown) …

Are two images not possible in the same custom element?

Here, my code snippets:

<?php
//controls.php
return array(
	'image' => array(
		'type' => 'image',
		'ui' => array(
			'title' => __( 'Image', 'my-extension' ),
      'tooltip' => __( 'Choose an image to display above your content.', 'my-extension' ),
		)
    ),
        'image_logo' => array(
            'type' => 'image',
            'ui' => array(
                'title' => __( 'Logo', 'my-extension' ),
        'tooltip' => __( 'Choose an logo to display under the title image.', 'my-extension' ),
            )
    )
  };
?>

<?php
//shortcode.php
	echo "
		<div >
			<img  src='{$image}'>
			<img  src='{$image_logo}'>
		</div>
";
?>

Hi There,

Thanks for writing in! Regretfully, this particular customization request is outside the scope of our support as this is not related to an issue with the theme and instead has to do with your customization of it. As such, you will need to investigate this particular issue on your own. Or you can use two [image shortcode] (http://demo.theme.co/integrity-1/shortcodes/images/) is one RAW Content element instead.

Thank you for your understanding.

So If not here, where else should I ask cornerstone questions?

Fortunately your colleague gave me a friendly hint in an another topic that all variables has to be defined in defaults.php as well so it was the whole issue. Now it’s solved.

Glad that you managed to fix the issue.
