title: Getting The Base64 of an Image from CameraRoll
body: <p>I'm trying to get the Base64 of an image from CameraRoll so I can pass it along to a third-party system. I don't want to use RN-Fetch-Blob. I've tried ImageStore, but it says I'm supplying an invalid URI. </p>
  
  <p>What's the best way to go about this? Does React-Native have the means? Or do I have to write something natively?</p>
