How to remove featured image from Portfolio pop-up in RokoPhoto

Buy default RokoPhoto's portfolio pop-up box shows the featured image, but it can be removed by following this tutorial. First of all, make sure that you're using a child theme to do that.

Copy /sections/portfolio.php file to your child theme and remove the following code from it:

<?php 
	$image_id = get_post_thumbnail_id();
	$modal_mobile = wp_get_attachment_image_src($image_id,'thumbnail_portfolio_mobile', true);
?>
<picture>
	<source srcset="<?php echo $modal_mobile[0]; ?>" media="(max-width: 460px)">
	<?php the_post_thumbnail( 'thumbnail_portfolio_modal', array( 'class' => "img-responsive")); ?>
</picture>

And save your changes, and that will do.
