React Native Image

This post will give you an idea to Display Image in React Native Using Image Component. React Native Image is a component for displaying different types of images, including network images, static resources, temporary local images, and images from local disks, such as the camera roll.

To Import Image in the Code

import { Image } from 'react-native'

Render using

Below are the 4 different ways to display different image sources.

1. Static Image Resources

<Image 
    source={require('./your-img.png')}  
    style={{width: 400, height: 400}} 
/>

require can also be used for including audio, video or document files in your project. Most common .mp3, .wav, .mp4, .mov, .html and .pdf.

2. Network Requests for Images

<Image 
    source={{uri: 'https://raw.githubusercontent.com/AboutReact/sampleresource/master/sample_img.png'}} 
    style={{width: 400, height: 400}} 
/>

3. Uri Data Images

<Image 
    style={{width: 66, height: 58}} 
    source={{uri:'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg=='}}
/>

4. SVG Images

To use SVG image from the image folder of your project you need to install a library from your terminal using

npm install react-native-remote-svg --save

Now import Image from it using

import {Image} from ‘react-native-remote-svg’

That was the different ways which will be very helpful for you to show the image from different resources. Now let’s move towards the React Native Image Example.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X

react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Code

Open App.js in any code editor and replace the code with the following code.

App.js

//React Native Image
//https://aboutreact.com/react-native-image/

//import React in our code
import React from 'react';

//import all the components we are going to use
import { StyleSheet, View, Text, SafeAreaView, Image } from 'react-native';

const App = () => {
  return (
    <SafeAreaView style={{ flex: 1 }}>
      <View style={styles.container}>
        <Image
          source={{
            uri:
              'https://raw.githubusercontent.com/AboutReact/sampleresource/master/sample_img.png',
          }}
          style={{ width: 400, height: 400, margin: 16 }}
        />
        {/* If you want to show image from local directory
          <Image 
            source={require('./your-img.png')}  
            style={{width: 400, height: 400}} 
          />
        */}
        <Image
          style={{ width: 66, height: 58 }}
          source={{
            uri:
              'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg==',
          }}
        />
      </View>
    </SafeAreaView>
  );
};
const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    paddingTop: 40,
    backgroundColor: '#ecf0f1',
  },
});
export default App;

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

To run the project on an Android Virtual Device or on real debugging device

react-native run-android

or on the iOS Simulator by running (macOS only)

react-native run-ios
