Hey, I am very new to processwire and bootstrap. I have a field (text area) and there I want to be able to insert an image which is responsive. I tryed it with Source but in the end the page doesn't seem to like it when I insert in Source the following code <img src="<?php echo $homepage->content_img->url; ?>" class="img-fluid" alt="Responsive image"> What can I do to make it possible to insert reponsive images in a text area? Thank you in advance. Marcel
