nice plugin but stubborn about https

been using this plugin for a while, very nice, good job. switched blog to https, and this plugin started breaking the https, loading its stars over http. i tried everything, i would set star with its https URL, but plugin would still stubbornly use https:// URL instead.. eventually i had to reupload stars as new images into media library, and finally it worked fined, https staying unbroken. this was really annoying..
