$size is not used, you could remove the assignment.

            $dimg = imagecreatefromstring(base64_decode($dd->digits[$this->iNumber[$i]][1]));
            imagecopy($img, $dimg, $start, 0, 0, 0, imagesx($dimg), $dd->iHeight);
            $start += imagesx($dimg);
        }
        $resimg = @imagecreatetruecolor($start + 4, $dd->iHeight + 4);
        if ($resimg < 1) {
            return false;
        }
        imagecopy($resimg, $img, 2, 2, 0, 0, $start, $dd->iHeight);
        header("Content-type: image/jpeg");
        imagejpeg($resimg);
