title: Save image from URL to device with React Native
body: <p>Hi as title suggests I need to save images to Android device from my CDN.</p>
  
  <p>I am building app with React Native, and what I've done is that:</p>
  
  <p><code>fetch('https://server.com/images.json').then((json) =&gt; console.log(json))</code></p>
  
  <p>Which returns json: </p>
  
  <p><code>{images: ["cdn.server.com/image1.jpg", "cdn.server.com/image2.jpg"]}</code></p>
  
  <p>And now I really don't know what to do to save images to my device, because then I need to use them to open Instagram Intent (<a href="https://www.instagram.com/developer/mobile-sharing/android-intents/" rel="nofollow">https://www.instagram.com/developer/mobile-sharing/android-intents/</a>) and it only works if image is saved to device.</p>
  
  <p>Any ideas?</p>
