title: React Native Webview - With Expo - Not displaying Images from s3 bucket
body: <p>Trying to display an image within a WebView in ReactNative (Using Expo).  Doing this to allow image zooming. </p>
  
  <p>Using webview with source={{ uri: this.state.imageUrl }}  which is an s3 bucket image location.   ie-- ending in .jpg</p>
  
  <p>I have set mixedContentMode to 'always' as is suggested by people with similar problems, along with setting javascriptEnabled and domStorage to true, setting style to flex:1 etc etc. </p>
  
  <p>My android is displaying a white page only, but iOS displays the image just fine, so url is not the problem. </p>
  
  <p>I know RN advertises Webview as being soon to be deprecated and to use react-native-webview.  But as we use Expo this isn't an option as linking is required to use react-native-webview which cannot be done with expo. </p>
  
  <p>Is there something I have missed with s3 buckets or has anyone else had a similar issue they have managed to solve this issue?   Not sure what else to try, have used the trick with google drive prefix elsewhere in the app for displaying PDFs in the webview but that doesnt work in this case.  And using mixedContentMode hasn't solved anything.</p>
  
  <pre><code>&lt;WebView
                    source={{ uri: this.props.map.source }}
                      startInLoadingState
                      javaScriptEnabled
                      style={{ flex: 1}}
                      scalesPageToFit
                      javaScriptEnabled
                      domStorageEnabled
                      originWhitelist={['*']}
                      mixedContentMode='always'
                  /&gt;
  </code></pre>
  
  <p>and example of the image url is '<a href="https://example-uploads.s3.ap-southeast-2.amazonaws.com/uploads/users/ap-southeast-2:example/public/image-hd-1.jpg" rel="nofollow noreferrer">https://example-uploads.s3.ap-southeast-2.amazonaws.com/uploads/users/ap-southeast-2:example/public/image-hd-1.jpg</a>'</p>
  
  <p>just showing the format.. above url will not work</p>
