title: Saving images after altering them by CamanJS plugin
body: <p>So I have some images and I could sucessfuly apply effects to them by using the CamanJS plugin. But now I want to save these altered images and replace them with the original one.</p>
  
  <p>The documentation (<a href="https://github.com/meltingice/CamanJS/wiki/How-to-use#saving-images">link</a>) Provides information on saving images. but it is seen as a download prompt. I want the images to be saved at the server without a prompt and on the click of the "save" button. </p>
  
  <p>The documentation also says something about base64 encoding which I dont understand. Could my problem be solved?
  thanks!.  </p>
