title: Convert Base64 to normal PNG for copy/pasting
body: <p>I've got an HTML email template that's using a kludgy process as follows:</p>
  
  <ol>
  <li>Pull data from MySQL and put it into a HighCharts chart</li>
  <li>Convert the HighCharts SVG to canvas using canvg</li>
  <li>Render the canvas as a Base64 PNG using canvas.toDataURL</li>
  </ol>
  
  <p>All's well and good, the image shows up fine (except for some quirkiness in Internet Explorer), but here's the rub:</p>
  
  <p>I'd like users to be able to copy and paste the entire web page into Outlook and send it out as an email. However, Outlook (and a few other clients I've tried) won't receive Base64 PNGs via copy paste -- there's a blank space where the image should be.</p>
  
  <p>Does anyone know of a way to convert the Base64 into a normal PNG such that it can survive the copy/paste? Maybe this requires saving the PNG to server?</p>
