title: How to solve local caching?
body: <p>My question is the next:</p>
  
  <p><strong>Situation:</strong>
  I have an <code>ImagesScreen</code> where I can upload some additional photos, delete them, etc.
  When someone add a new photo (from the gallery, react-native-image-crop), I want to make a copy from the image, save it to the local storage (so even if someone delete the image from the gallery I got my own copy in my local storage).</p>
  
  <p><strong>Why:</strong>
  I do not want to immediately send the photos toward the API, I just want to backup them every day, so when I make a copy from the selected photo(s) I want to retrieve the uri of the local stored image. (not the uri of the image in the gallery)</p>
  
  <p>How would you guys handle this case?</p>
