title: Firebase : Best way to store multiple image URLs
body: <p>Just a quick message to ask you about how to store images URLs in Firebase Database for later use.
  Let me explain:</p>
  
  <p>I use Firebase Storage to store Images but store their respective URLs in Firebase Database, separately from Firebase Storage (as I have been reading on here it was the way to do it).<br>
  So in Firebase Database I have a "ItemPictures" Node where I want to store up to 5 pictures URLs per Item.</p>
  
  <p>But I don't know what is the best way to store multiple image URLs of a same Item:<br> 
  - Creating a List with random ids using push() (and then having to manage deleting manually the picture'sURL when it gets updated).<br> 
  - Creating a "Picture" Object with 5 URLs String values, making it easier to locate and navigate through.</p>
  
  <p>The thing is that later on I will need those URLs to populate a View Pager with the 5 pictures.</p>
  
  <p>Cheers,</p>
