	      <?php
	      function LoadJpeg($imgname)
	      {
		  /* Attempt to open */
		  $im = @imagecreatefromjpeg($imgname);

		  /* See if it failed */
		  if(!$im)
		  {
		      /* Create a black image */
		      $im  = imagecreatetruecolor(150, 30);
		      $bgc = imagecolorallocate($im, 255, 255, 255);
		      $tc  = imagecolorallocate($im, 0, 0, 0);

		      imagefilledrectangle($im, 0, 0, 150, 30, $bgc);

		      /* Output an error message */
		      imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);
		  }

		  return $im;
	      }

	      header('Content-Type: image/jpeg');

	      $img = LoadJpeg('bogus.image');

	      imagejpeg($img);
	      imagedestroy($img);
