Note that image sources required this way include size (width, height) info for the Image. If you need to scale the image dynamically (i.e. via flex), you may need to manually set { width: undefined, height: undefined } on the style attribute.
**Available React Native 0.14+**. If you've generated your project with 0.13 or earlier, read this. The new asset system relies on build hooks for [Xcode](https://github.com/facebook/react-native/pull/3523) and [Gradle](https://github.com/facebook/react-native/commit/9dc036d2b99e6233297c55a3490bfc308e34e75f) that are included in new projects generated with `react-native init`. If you generated your projects before that, you'll have to manually add them to your projects to use the new images asset system. See [Upgrading](/react-native/docs/upgrading.html) for instructions on how to do this.
