Trouble requiring image module in React Native

Just getting started with React-Native and I'm having some trouble requiring a static image.

Here's the very-basic code I have so far:

'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  Image,
  View,
} = React;

var buzz = React.createClass({
  render: function() {
    return (
      <View style={styles.container}>
        <Image source={require('image!bg')}  style={styles.bg}>
          <Text style={styles.welcome}>
            Welcome to Buzz! iOS interface to
          </Text>
          <Text style={styles.welcomeHeader}>Charityware</Text>
        </Image>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: 'transparent'
  },
  welcomeHeader: {
    fontWeight: '600',
    fontFamily: 'Helvetica',
    color: '#fff',
    fontSize: 50,
    alignSelf: 'center'
  },
  bg: {
    width: 400,
    height: 300,
    alignSelf: 'auto',

  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
  },
});

AppRegistry.registerComponent('buzz', () => buzz);

The main trouble area is:

    <Image source={require('image!bg')}  style={styles.bg}>
      <Text style={styles.welcome}>
        Welcome to Buzz! iOS interface to
      </Text>
      <Text style={styles.welcomeHeader}>Charityware</Text>
    </Image>

When packaging my app and running it, I get a render error:

I understand that you need to add images in xcode as an image set in order for the require call to find the image and have added an image set to that end:

...But to no avail. Anyone have any thoughts? I've read the docs and seem to be doing this in the prescribed way. Thanks!

Since React Native release 0.14 the handling of images has been normalized for iOS and Android and is now different. I could not find any documentation except for this very clear commit note on Github: Document new asset system.

There's only a screenshot of the proposed documentation:

Update: There is a link now for the real documentation: https://facebook.github.io/react-native/docs/images.html

I had similar problem, then renamed the image files in file system under the xcode project's Images.xcassets directories with suffixes and capitalization to match the image I'm loading.

For example, if source={require('image!Villagers')} it required the image files named precisely as Villagers.png, [email protected] and [email protected]. If the '@3x' part of filename wasn't there, the image would not get found.

What version of React Native are you running? There was an issue with the packager, related to that, that have been solved.

If that's the case, you can either update or run the dev server with:

node_modules/react-native/packager/packager.sh --assetRoots path/to/Images.xcassets

https://github.com/facebook/react-native/issues/282

This question has already been answered, but if you use React Native on Android, you might have that same problem. For me, solution was using source={{ uri: "google", isStatic: true }} instead of source={required('./bg.png')}.

Just don't forget to add your images in src/main/res/drawable folder.

NOTE: App build required for new resources Any time you add a new resource to Images.xcassets you will need to re->build your app through XCode before you can use it - a reload from within >the simulator is not enough. (from React Native docs https://facebook.github.io/react-native/docs/image.html#content)

Also make sure to restart the packager. That solved the issue for me.
