Use with a local file

Question

The documentation says that the only way to reference a static image is to use require.

But I\'m not sure where does react expect to have those images. The examples don

Answer 1

Using React Native 0.41 (in March 2017), targeting iOS, I just found it as easy as:

<Image source={require('./myimage.png')} />

The image file must exist in the same folder as the .js file requiring it.

I didn't have to change anything in the XCode project. It just worked. Maybe things have changed a lot in 2 years!

Note that if the filename has anything other than lower-case letters, or the path is anything more than "./", then for me, it started failing. Not sure what the restrictions are, but start simple and work forward.

Hope this helps someone, as many other answers here seem overly complex and full of (naughty) off-site links.

UPDATE: BTW - The official documentation for this is here: https://facebook.github.io/react-native/docs/images.html

Answer 2

I had this exact same issue until I realized I hadn't put the image in my Image.xcassets. I was able to drag and drop it into Xcode with Image.xcassets open and after rebuilding, it fixed the problem!

Answer 3

From the UIExplorer sample app:

Static assets should be required by prefixing with image! and are located in the app bundle.

So like this:

render: function() {
  return (
    <View style={styles.horizontal}>
      <Image source={require('image!uie_thumb_normal')} style={styles.icon} />
      <Image source={require('image!uie_thumb_selected')} style={styles.icon} />
      <Image source={require('image!uie_comment_normal')} style={styles.icon} />
      <Image source={require('image!uie_comment_highlighted')} style={styles.icon} />
    </View>
  );
}

ES6 solution:

import DefaultImage from '../assets/image.png';

const DEFAULT_IMAGE = Image.resolveAssetSource(DefaultImage).uri;

and then:

<Image source={{uri: DEFAULT_IMAGE}} />

Answer 5

You have to add to the source property an object with a property called "uri" where you can specify the path of your image as you can see in the following example:

<Image style={styles.image} source={{uri: "http://www.mysyte.com/myimage.jpg"}} />

remember then to set the width and height via the style property:

var styles = StyleSheet.create({
   image:{
    width: 360,
    height: 40,
  }
});

It works exactly as you expect it to work. There's a bug https://github.com/facebook/react-native/issues/282 that prevents it from working correctly.

If you have node_modules (with react_native) in the same folder as the xcode project, you can edit node_modules/react-native/packager/packager.js and make this change: https://github.com/facebook/react-native/pull/286/files . It'll work magically :)

If your react_native is installed somewhere else and the patch doesn't work, comment on https://github.com/facebook/react-native/issues/282 to let them know about your setup.
