썸네일 생성시 에러가 6가지나 나옵니다.

그누보드4에서 사용하던 dq thumb engine을 그누보드5에서도 사용하려고 하는데 아래와 같은 에러가 나옵니다.

Warning: fopen(http://seto.com/data/file/j_issue/_5.thumb.work): failed to open stream: HTTP wrapper does not support writeable connections in /home/jung/public_html/thumbEngine/dq_thumb_engine2.php on line 203

해당 소스는 아래와 같습니다.

if (($gd_info['JPG Support']||$gd_info['PNG Support']||$gd_info['GIF Create Support']) && preg_match('/'.$file_type.'/i',$_gd_support)) {

                $_fThumbWorkFile = $_fThumbnail.".work";
                if(!file_exists($_fThumbWorkFile)) {
                    $fp = fopen($_fThumbWorkFile, "w");
                    fwrite($fp, "Thumbnail image create works file");
                    fclose($fp);
                }

그리고..

chmod($_fThumbnail,0706);
                ImageDestroy($dst_img);
                ImageDestroy($src_img);

                unlink($_fThumbWorkFile);

경험하지 못한 내용들이라 어려운데 답변 주시면 감사하겠습니다.
