And just FYI, there are some other scripts running on the Add listing page as well as my cut/copy/past PHP skills don’t allow me to merge them all. 
**Image required:**
*add_filter(*
* 'hivepress/v1/forms/listing_update/errors',*
* function( $errors, $form ) {*
* $listing = $form->get_model();*
* if ( $listing && ! count($listing->get_images__id()) > 1 ) {*
* $errors[] = 'Please upload at least one image for this listing.';*
* }*
* return $errors;*
* },*
* 100,*
* 2*
*);*
*add_filter(*
* 'hivepress/v1/forms/listing_update',*
* function( $form ) {*
* $form['fields']['images']['statuses']['optional'] = null;*
* return $form;*
* },*
* 1000*

**Field Labels and Descriptions:**
*add_filter(*

**Extras field option:**
