How to create GD Image from base64 encoded jpeg?

Question

I have an upload Api that as a response object delivers (along with other stuff inside a Json object) a base64 encoded jpeg image.

I create the encoded image as so:

$im; // gd image resource
ob_start();
imagejpeg($im);
$data = base64_encode(ob_get_clean());

The data then is put inside a form field using javascript and submitted.

How can I create a GD resource from that again so that I actually can save that image as a file?

Everything in PHP.

Are you sure you need to do that extra step? How about:

file_put_contents('MyFile.jpg', base64_decode($_POST['MyFormField']));
