title: Upload images into a file server and store the url to the image using nodejs
body: <p>I am implementing a web app using <code>MEAN Stack</code> and <code>Angular 6</code>. There I want to submit a form with file upload. <code>'.png'</code> files should be uploaded.</p>
  
  <p>I want to save the file in a different file server and send the url to the image.Currently I upload files into a folder in my project and save the image in db (I used <code>ng2fileupload</code> and <code>multer</code> for that.). Then it saves like this. </p>
  
  <pre><code>"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAV4AAAFUCAYAAABssFR8AAAK..."
  </code></pre>
  
  <p>But I want to save the image url and the image should be retrived by the url. Does anyone can explain a proper method for that?</p>
