title: Storing photos on device: Local Database vs. Gallery
body: <p>I'm working an iOS app that publishes photos to other users, and the sent photos are not stored on the server.
  The user must have the history of his photos and related info.<br/><br/>
  Should I store the photos in Local DB or in the Photos Gallery?
  I'm worried that if the photos are stored in the gallery, the user might delete them without understanding this erases the app's history.<br/><br/>
  Thank you.</p>
