I'm getting from an external source a PNG image in raw format (encoded in base64).

And with this code I'll echo on the screen.

Code:


$img=base64_decode($_POST['img']);

header("Content-type: image/png");
echo $img;


How can I check if the datas received are real PNG raw (and not malicious code) ?
