   // it will show the loaded image in the browser
   header('Content-type: image/jpg');

Example 3 − Handling errors during loading of a JPEG image

   function LoadJpeg($imgname) {
      /* Attempt to open */
      $im = @imagecreatefromjpeg($imgname);
      /* See if it failed */
      if(!$im) {
         /* Create a black image */
         $im = imagecreatetruecolor(700, 300);
         $bgc = imagecolorallocate($im, 0, 0, 255);
         $tc = imagecolorallocate($im, 255,255, 255);
         imagefilledrectangle($im, 0, 0, 700, 300, $bgc);
         /* Output an error message */
         imagestring($im, 20, 80, 80, 'Error loading ' . $imgname, $tc);
      return $im;
   header('Content-Type: image/jpeg');
   $img = LoadJpeg('bogus.image');
