title: ionic save photo to device
body: <p>I'm using the following code to get to access the device Photo Library,
  however it is retuning base64 encoded string, so I am a bit confused on what to do with this information. I would like to store the photo to the application storage directory (not the device photo album) then get the image URL so I can add it to the user DB.</p>
  
  <pre><code>takePhoto() {
  console.log('take photo')
  const options: CameraOptions = {
    quality: 100,
    destinationType: this.camera.DestinationType.DATA_URL,
    encodingType: this.camera.EncodingType.JPEG,
    mediaType: this.camera.MediaType.PICTURE,
    sourceType: this.camera.PictureSourceType.PHOTOLIBRARY
  }
  this.camera.getPicture(options).then((imageData) =&gt; {
    // imageData is either a base64 encoded string or a file URI
    // If it's base64:
    console.log(imageData)
    let base64Image = 'data:image/jpeg;base64,' + imageData;
  
  }, (err) =&gt; {
    // Handle error
    console.log('camera error')
    console.log(err)
  });
  </code></pre>
