PHP curl download image when sent chunked - php

Question

For downloading image I use this script:
<?php
function download_image($url, $save_to) {
if(file_exists($save_to))
unlink($save_to);
$ch = curl_init();
curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$result = curl_exec($ch);
curl_close($ch);
$fp = fopen($save_to, 'w');
fwrite($fp, $result);
fclose($fp);
chmod($save_to, 0777);
}
$url = "http://flo.cubecdn.net/media/catalog/product/cache/1/image/400x400/9df78eab33525d08d6e5fb8d27136e95/4/0/4050266152131_1.jpg";
download_image($url, "download.jpg");
?>
When script finishes downloading, it saves file as download.jpg. But it is not jpeg file. What can be the problem?

EDIT 2:
I think the problem is when server sends image:
Transfer-Encoding: chunked
Because I can not get image even with wget
