How to change the blacklist image name

There are some common images such as emojis and emoticons that are filtered out of the feed. If you want to exclude any other image from the feed shortcode output then you can use the following code in your theme's functions.php file: 

function tifd_feedzy_blacklist_images( $blacklist ) {
    $blacklist[] = 'xxxx';
    return $blacklist;
}
add_filter( 'feedzy_feed_blacklist_images', 'tifd_feedzy_blacklist_images' );

Replace xxx with the image name.
