The Image Carousel does not support filtering by media taxonomies out of the box.

For example, the following shortcode won’t work:

[su_image_carousel source="taxonomy: media_category: 1, 2, 3"]

Support can be enabled by adding the following code to the end of the functions.php file of an active theme:

add_filter( 'su/get_gallery_slides_query', function( $query, $source, $args ) {

	// Replace 'media_category' with your taxonomy name
	if ( 'media_category' === $source['tax'] ) {
		$query['post_mime_type'] = 'image/jpeg,image/gif,image/jpg,image/png';
		$query['post_type']      = 'attachment';
		$query['post_status']    = 'inherit';
	}

	return $query;

} );
