从其他主机获取网站

I want to get the content of a domain, but from a different host (IP) than specified in the current A-Records.

I've solved this using cURL:

$headers = array("Host: www.example.com");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$ip = "12.31.23.123";
$goto = "http://" . $ip . $_SERVER["REQUEST_URI"];
curl_setopt($ch, CURLOPT_URL, "$goto");

But i also need a way to get the images from the host!

Right now i only get the HTML code with cURL.

Any ideas?

Maybe a way to make the visitor download the image from the correct IP?
