Laravel 5.2: how create image file from json

In my controller i receive from form data like this:

"output":{"width":500,"height":500,"image":"data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAEBAQEBAQEBAQEBAQFAH/9k=..."},"actions":{"crop":{"x":97,"y":0,"height":500,"width":500},"size":null}}[

Can I create image file from this data?

upd 1. Decode the json - ok, pull out the image data - ok, decode the base64 - ok, but when I try write to disk then I got error: NotReadableException in Decoder.php line 96: Unable to init from given binary data.

$file = Request::input('photo');
$imagedata=json_decode($file);
$file=$imagedata->output->image;
$image = base64_decode($file);

$png_url = "user-".time().".png";
$path = "/public/".$png_url;

Image::make($image)->save($path);

upd 2. Solved with file_put_contents function.

This is working:

$file = Request::input('photo');
$imagedata=json_decode($file);
$file=$imagedata->output->image;
$png_url = "user-".time().".png";
$path = "uploads/".$png_url;
$image = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $file));
file_put_contents($path, $image);

here is how you can save image from a json data:

$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
    . 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'
    . 'EX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r'
    . '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);

$im = imagecreatefromstring($data);
if ($im !== false) {
    echo imagejpeg($im , base_path() . DIRECTORY_SEPARATOR . "sth.jpeg") ;
}
else {
    echo 'An error occurred.';
}
