Need to consider:

        /*if ($type == 2) {
            $cimtag = 'div';
        } else { // Type is 4. */
            $cimboxattr['href'] = new moodle_url('/course/view.php', array('id' => $course->id));
            $cimtag = 'a';
        //}
        $contentimages .= html_writer::tag($cimtag, '', $cimboxattr);
