'uploadfile/thumb/'. $fileName;} else {src=imagecreatefromjpeg (imgPath); srcw=imagesx (src_w = imagesx (srcw=imagesx (src); srch=imagesy (src_h = imagesy (srch=imagesy (src)); / / set thumbnail size $dst_w = $src_w1;$dst_h = $src_h2;dst=imagecreatetruecolor (dst_w,dsth); / / Image sampling copy imagecopyresampled (dst_h); / / Image sampling copy imagecopyresampled (dsth)) / / copy imagecopyresampled (dst,src,0,0,0,0,src,0,0,0,0,src,0,0,0,0,dst_w,dsth,dst_h,dst h, src_w,srch); / / Save thumbnail imagejpeg (src_h); / / Save thumbnail imagejpeg (srch); / / Save thumbnail imagejpeg (dst,thumbPath); / / destroy resource imagedestroy (src); imagedestroy ($dst) ThumbPath=strreplace (PHPCMSPATH, "/", thumbPath=str _ replace (PHPCMS_PATH, "/", thumbPath=strreplace (PHPCMSPATH, "/", thumbPath); return $thumbPath;}}
