The <Image> component cannot contain children. If you want to render content on top of the image, consider using absolute positioning

Since react-native 0.50 you can't nest components inside <Image> tag, rather you have to use <ImageBackground> for background images. Release Notes for v0.50.0

You are not allowed to put other components inside an image component. You need to wrap a View around your Image and positioned it as absolute.

<View style={{ flex: 1}}>
<Image source={bgImage} style={styles.backgroundContainer} /> 
<View style={styles.container}>
    <Quote quoteText={this.props.text} quoteSource={this.props.source}/>
</View>
</View>


container: {
    position: 'absolute',
    top: 0,
    bottom: 0,
    left: 0,
    right: 0, 
    justifyContent: 'center',
    alignItems: 'center',
  },

EDIT: Since react-native version 50.0, you can simply use ImageBackground
