title: React Native local images load slowly
body: <p>I'm building an app using React Native with Expo. Everything works fine except the images, they load correctly but it takes about 2 seconds to load, and it's weird because all the images are local images and they are light too, so they should load instantly. This problem occurs also after I build and get the .apk on my android device so the images are always stored locally.<br><br>
  This is a portion of the main page of my app:</p>
  
  <pre><code>...
     &lt;View style={styles.bottomItem}&gt;
       &lt;View style={styles.bottomItemInnerFirst}&gt;
         &lt;TouchableOpacity onPress={() =&gt; this.props.navigation.navigate('SecondPage')}&gt;
           &lt;Image
             source={require('../assets/images/iconT.jpg')}
             style={{width: '100%', height: '100%'}}
             resizeMode='contain'
           /&gt;
         &lt;/TouchableOpacity&gt;
       &lt;/View&gt;
     &lt;/View&gt;
  ...
  </code></pre>
  
  <p>The problem occurs not only with the Image tag but also with ImageBackground.
  I've looked at this doc too <a href="https://docs.expo.io/versions/latest/guides/preloading-and-caching-assets/" rel="noreferrer">https://docs.expo.io/versions/latest/guides/preloading-and-caching-assets/</a>
  but I'm using local images and I don't know what to do to make it work.</p>
