public class ImagesActionHandler
extends BaseActionHandler
implements PortalAccessible

This ActionHandler implements the DELETE and GETSIZE actions which are used by the ImageBLOB reference components in the OB3 windows. The DELETE action deletes an image from the database, and its reference from the referencing table The GETSIZE action gets the size of an image. If the image doesn't yet have size properties, it will create them and save them in the image object in the database. Also, it will compute the MIME type if it hasn't yet been computed
