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.

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

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

A quick way would be to try and make an image with the GD library.
Something like:
if (imagecreatefromstring($img)) {
	header("Content-type:image/png");
	echo $img;
}

Perhaps check the image header matches the correct format for a PNG image.
