title: in Ionic 2, How should I store images?
body: <p>I am making an hybrid mobile app using Ionic 2, in which I am pretty new. In the app I have to show images from distant URLs after sending a query that returns the list of URLs for the images to show (this part is OK). But I was wondering, because I want my app to work offline (after having used it online at least once for some initial data), how should I store the images using <code>@ionic/storage</code>'s <code>Storage</code> provider ?</p>
  
  <p>Can I consider saving base64 strings in ionic key/value SQLite / IndexedDB default storage or is there a cleaner way to do this ?</p>
