title: How to show other users information (such as photos or usernames) using Firebase?
body: <p>I'm currently working on an Firebase android application, and after doing some <a href="https://stackoverflow.com/questions/38103407/am-i-able-to-load-another-users-profile-image-in-firebase-android">research</a> it seems that Firebase doesn't allow apps to display user information other than the logged in user, for security reasons. </p>
  
  <p>I would like to know then what are some secure ways to do so, or how is it usually done, because what is the point of having profile pictures and other information if you can't show them to other users anyway?</p>
  
  <p>For example, should I save a profile picture copy on Firebase Storage for each user? How should I link the actual images to their corresponding user? What about other relevant information about the user, should I create a "User" node in firebase database that somehow links to the original user in "authentication"? </p>
