Doesn't work correctly on https

I was able to fix it in attachment.php by inserting these lines:

$orig_url = $url;
$url = preg_replace("/https?:\/\//", '', $url);
$home = preg_replace("/https?:\/\//", '', $home);

just before this line:

$filename = ABSPATH . substr($url, strlen($home) + 1);

and by changing this line:

'url' => $url,

to:

'url' => $orig_url,

i’m sure there’s a more elegant way to fix it, but here’s my messy attempt.

thanks!
