CMS4 Image selection - BUG

When trying to delete an image instance that is in use the javascript popup says "DeleteImageSizeInstance Going nowhere" instead of "That image instance is in use, so it cannot be deleted"

CMS4 - needs button to clear all pages in a folder that dont exist in the database - also those that are hidden as an option
