Absolute path of remote images

[bluemoonballoon]

I'm building a site for a client that has a feature similar to the way Facebook grabs images from a url you enter (ajax?). I've tried for days and I can't seem to find a simple way to get absolute image paths from a remote url. I can get the relative ones just fine, though.

Any thoughts? This is driving me nuts.

Get the address from the user inputed URL (such as http://google.com) and append the relative image path (images/image.gif):

$url = $_GET['url'];
$image_path = "images/image.gif";
if(file_get_contents($url)){
     $url += $image_path;
}

There's probably better ways of doing it, and of course you'd have to check to make sure there are no variables and such attached to the url.

That works fine unless you have an image path like this: "../../images/01.jpg"
