Hi @jonathan
I had selected “Image URL” in Return Value at my image repeater.
I tried your method, but no image output is being echoed.
It showed this in the site elements:
<div class="contact-image" style="background-image: url(<br />
<b>Warning</b>: Illegal string offset 'url' in <b>C:\xampp\htdocs\highheels\wp-content\themes\naked-wordpress-master\page-contact.php</b> on line <b>28</b><br />
h);"></div>
