title: Froala editor v2.3.4 insert image -> just insert into DOM as "data:image" no upload to server
body: <p>I'm using Froala editor v2.3.4 and I have the <code>insertImage</code> plugin using the file <code>2.3.4/js//image.min.js</code>, which activated without additional parameters. </p>
  
  <p>Every time I instert an image, it gets uploaded to 
  <a href="https://i.stack.imgur.com/qxyZ5.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qxyZ5.jpg" alt="enter image description here"></a></p>
  
  <p>I want that the image gets entered into the DOM tree with the <code>src="data:image"</code></p>
  
  <p>I get this behavior by setting the <code>imageUploadURL</code> parameter and with an invalid URL:  <a href="https://i.stack.imgur.com/Daash.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Daash.jpg" alt="enter image description here"></a></p>
  
  <p>The result is that the HTML code looks like this:
  <a href="https://i.stack.imgur.com/4OcOy.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4OcOy.jpg" alt="enter image description here"></a></p>
  
  <p>The image is not uploaded but just added to the DOM as a base64 encoded string. That is exactly what I want. But, of course, I got an error: <a href="https://i.stack.imgur.com/lfrk9.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lfrk9.jpg" alt="enter image description here"></a> </p>
  
  <p>Is there an option in the Froala editor v2, which 
  disables the image upload to a server ( not the possibility to insert images into the editor field ) and stores inserted images as <code>src="data:image</code>?</p>
