i trying upload images using import.csv file. images need resized before uploading. using code uploading returning black image of given size.

 <?php error_reporting(e_all); include('config.php'); include('inc/header.php'); define('csv_path', ''); $csv_file = csv_path . "importimage.csv"; // name of csv file $csvfile  = fopen($csv_file, 'r'); $thedata  = fgets($csvfile);  $i = 0; while (!feof($csvfile)) {      $csv_data[] = fgets($csvfile, 1024);      $csv_array  = explode(",", $csv_data[$i]);     $insert_csv = array();     $url        = $insert_csv['url'] = $csv_array[0];     $image      = $insert_csv['image'] = $csv_array[1];      $raw = file_get_contents($url . $image);       /*resize using gd*/       /*      * php gd      * resize image using gd library      */      // file , new size     //the original image has 800x600     $filename = $raw;     //the resize percent of original size     $percent  = 0.5;      // content type     header('content-type: image/jpeg');       // new sizes     list($width, $height) = getimagesize($filename);     $newwidth  = 200;     $newheight = 200;      // load     $thumb  = imagecreate($newwidth, $newheight);     $source = imagecreate($filename);      // resize     $imgnew = imagecopyresampled($thumb, $source, 0, 0, 0, 0, newwidth, $newheight, $width, $height);      imagejpeg($thumb, 'mypath' . time() . '.jpg'); // save resized image                                             //output , free memory     imagedestroy($thumb);     $i++; }  fclose($csvfile);  echo "file data imported database!!"; mysql_close($connect);  ?>
