I am able to capture image .and it get stored at /storage/emulated/0/pictures(inside android device)…how can i access this image …i red that we can use ionic native native storage to acess the device files … i saw the following code in ionic site…please help me in using this to access my image

import { NativeStorage } from 'ionic-native';
NativeStorage.setItem('myitem', {property: 'value', anotherProperty: 'anotherValue'})then(
      () => console.log('Stored item!'),
    error => console.error('Error storing item', error)
     );
  NativeStorage.getItem('myitem')
.then(
 data => console.log(data),
 error => console.error(error)
 );

my code for capturing image

takePicture(){
Camera.getPicture({
  quality : 95,
  destinationType : Camera.DestinationType.DATA_URL,
  sourceType : Camera.PictureSourceType.CAMERA,
  allowEdit : true,
  encodingType: Camera.EncodingType.PNG,
  targetWidth: 500,
  targetHeight: 500,
  saveToPhotoAlbum: true
}).then(imageData => {
  const b64toBlob = (b64Data, contentType='', sliceSize=512) => {
    const byteCharacters = atob(b64Data);
    const byteArrays = [];

    for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
      const slice = byteCharacters.slice(offset, offset + sliceSize);

      const byteNumbers = new Array(slice.length);
      for (let i = 0; i < slice.length; i++) {
        byteNumbers[i] = slice.charCodeAt(i);
      }

      const byteArray = new Uint8Array(byteNumbers);

      byteArrays.push(byteArray);
    }

    const blob = new Blob(byteArrays, {type: contentType});
    return blob;
  }

  this.guestPicture = b64toBlob(imageData, 'image/png');

}, error => {
  console.log("ERROR -> " + JSON.stringify(error));
});
   }

actually i am trying to access this image in another typescript file( ie.not in the file that captures image)
