Acces-control-Allow-Origin

I have installed Dreamfactory version 2.0.2 using bitnami on Amazon EC2 machine. I am trying to get jpeg image from Amazon S3.
I am using Angular JS SDK.
But I keep getting the error .
"No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access."

My Dreamfactory CORS setting are properly set.
Origin : '*'
Path: '*'
Headers: '*'
Max Age: 0

I am able to create new file or folder on Amazon S3 using angularjs sdk but I am not able to get the image.
I am able to get the image by using 'POSTMAN rest client ' but not using any browser.

Here is my AngularJs code:

$http({
method: 'GET',
url: '/api/v2/filestorage/truck3.jpg',
download: 'true'

      }).success(function (result) {
        
        console.log(result);
               
        
      
      });

Please tell me what I am doing wrong.
