title: REACT DROPZONE: Get data:images after upload
body: <p>As topic, I want get <code>data:images</code> after upload. I get that if only upload one image. If multiple images how to array it in console? </p>
  
  <pre><code>constructor(props) {
    super(props);
    this.state = {
      image: null
    };
  }
  
  onDropMain(mainImage) {
      var that = this
      let reader = new FileReader()
      reader.readAsDataURL(mainImage[0])
      reader.onloadend = function() {
          var result = reader.result
          that.setState({
              mainImage: result
          });
      }
      console.log(reader);
  }
  </code></pre>
  
  <p>This is how I get single <code>data:images</code>, but how about multiple images? Anyone has experience in this? </p>
