Picture taken with camera is not displaying in the view (iOS)

Ionic Framework ionic-v3
1

Im having trouble displaying the photo taken in a view

my setup is:

global packages:
    @ionic/cli-utils : 1.5.0
    Cordova CLI      : 7.0.1 
    Ionic CLI        : 3.5.0
local packages:
    @ionic/app-scripts              : 1.3.12
    @ionic/cli-plugin-cordova       : 1.4.1
    @ionic/cli-plugin-ionic-angular : 1.3.2
    Cordova Platforms               : ios 4.3.1
    Ionic Framework                 : ionic-angular 3.4.2
System:
    Node       : v6.11.1
    OS         : macOS Sierra
    Xcode      : Xcode 8.2.1 Build version 8C1002 
    ios-deploy : not installed
    ios-sim    : not installed
    npm        : 5.3.0

For the photo im using the next code:

base64Image: string[] = [];
takePicture(){
  const options: CameraOptions = {
    quality: 80,
    destinationType: this.camera.DestinationType.DATA_URL,
    encodingType: this.camera.EncodingType.JPEG,
    mediaType: this.camera.MediaType.PICTURE,
    sourceType: this.camera.PictureSourceType.CAMERA,
  };
  this.camera.getPicture(options)
  .then((imageData) => {
    if (this.flag == false) {
      this.base64Image.push('data:image/jpeg;base64,' + imageData);
    }else{
      this.base64Image.push('data:image/jpeg;base64,' + imageData);
      this.buttonFlag=true;
    }
    this.countFlag = true;
  })
  .catch((err) => {
    console.log(err);
    this.presentToast(err);
    // this.flag=true;
  });
  }

In the html I have the next:

<ion-content padding>
       <p>test</p>
       <p>Picture Taken</p>
       <img src={{base64Image[0]}}>
</ion-content padding>

Funny thing, a week ago, the first time I created de .ipa file the image showed up in the view after taking the picture, but two days later I just get a blank square on the view and cant figure out a way of fixing it. Also I have proved that the picture is taken since then upload it to Firebase Storage and get the download link.

upload() {
  let localuseruid = this.auth.userSession;
  let storageRef = firebase.storage().ref();
  let localtime = new Date().toLocaleString().replace('/', '-').replace('/', '-').replace(',', '').replace('AM', '').replace('PM', '');
    
  //Uploading img1
  const filename = 'IMG1'+localtime ;
  const imageRef = storageRef.child(`${this.globalVar.userStorageCurrentInstall}/${localuseruid.uid}/${filename}.jpg`);
  imageRef.putString(this.base64Image[0], firebase.storage.StringFormat.DATA_URL)
    .then((savedPicture) => {
      this.imgsLink.push(savedPicture.downloadURL);
      let data = this.datPro.update(this.globalVar.usersPath + localuseruid.uid + '/' + this.globalVar.userStorageCurrentInstall + '/' + localtime, {
        linkstage1: this.imgsLink[0],      
      });
    })
    .catch((err) => {
      this.presentToast(err);
    });
}

Thank you for the help.
