Remove or hide the first image (the main/featured image)

Hi what will be the code to remove or hide the first image attached (featured), so it will not display in .wlt_shortcode_media_wrapper in results, printing and search page. Thank you. I think there must be a way, since I saw something similar in forum. https://www.premiumpress.com/forums/topic/adding-an-image-to-fields-shortcode
but I really do not know anything about css or codes. Thanks
