Redactor upload and token

In L4 I was using Imperavi Redactor and it was simple to setup, and easy to use. With L5 I have big troubles setting the upload part of Redactor, mainly because of token verification. Below is the JS init part of Redactor and with 'imageUpload' I was able to get rid of the Token mismatch error.

<script type="text/javascript">
        $(function () {
            $('#content').redactor({
                minHeight: 300,
                maxHeight: 800,
                buttons: ['html', 'bold', 'italic', 'image', 'link'],
                imageUpload: 'uploadNewsImages?_token=' + '{{csrf_token()}}'
            });
        });
    </script>

But uploadNewsImages does not behave like in normal form upload situation. When i try this from Controller

dd($request->all());

I get Status Code:200 OK but in Network-Response bar of Developer I get this gibberish

So any idea where or what am I doing wrong, since this all was well in L4
