Image Picker - Loader and Image Quality

Ionic Framework ionic-v3
1

Hi Experts,

I am using following plugin to upload image in photo gallery.

I was looking for some help regarding 2 things:

  1. While images are being uploaded in the background, i want to show the loader to update the user on upload status.
  2. Images are being uploaded in Base64 format and even after giving the value=100 to quality parameter, image quality is really poor. Please suggest the best way to improve the image quality.

Thanks in advance.
