Massimo, I will try this. However, I've noticed that with the latest release 1.67.1 that the IS_NULL_OR(IS_UPLOAD_FILENAME()) and IS_NULL_OR (IS_IMAGE()) both seem to work in a manner that the IS_NULL_OR takes precedence in cases where the filename or image fields are empty. Did you make a change to support this, from now on? If not, then something strange is going on that it's working all of a sudden.
