Hi
I’ve recently published some further tutorials on uploading images to and retrieving images from Firebase storage in Ionic 2:
Part 1: http://masteringionic2.com/blog/2017-03-02-uploading-images-to-firebase-storage-with-ionic-2-part-1/
Part 2: http://masteringionic2.com/blog/2017-03-06-uploading-images-to-firebase-storage-with-ionic-2-part-2/
Hope these are useful for any ionites out there working with Firebase Storage
