Render images sources from parsed array of objects in react native

问题

I'm building a react native application which suppose to use some 'meta-data' objects as sources. I'm parsing each object in array and returning a JSX layout for each item. The only problem I have is how to provide sources from images, since I have them stored locally and need to require("link") them. My code gives me error:

function loadModuleImplementation(moduleId, module) {
  moduleId = "../../../images/icons/photographer/Party.png"

My code:

class SelectScreen extends Component {
  props:Props;


  Details = [
        {
          "type": "Party",
          "image": "../../../images/icons/photographer/Party.png"
        },
        {
          "type": "Wedding",
          "image": "../../../images/icons/photographer/Wedding.png"
        },
        {
          "type": "Architecture",
          "image": "../../../images/icons/photographer/Arhitecture.png"
        },
        {
          "type": "Christening",
          "image": "../../../images/icons/photographer/Christening.png"
        }
  ];

  render() {
    let renderPhotoTypes = () => {
      let type = [];

      this.Details.map( ( item )=> {
        type.push(
          <View style={styles.imageSelectItem} key={item.type}>
            <TouchableWithoutFeedback>
              <View>
                <View style={styles.imageContainer}>
                  <Image style={styles.image} source={require(item.image)}/>
                </View>
                <Text style={styles.text}>{item.type}</Text>
              </View>
            </TouchableWithoutFeedback>
          </View>
        );
      } );

      return type;
    };

    return (
      <ScrollView style={styleGuide.containerMain}>
        <Text style={styleGuide.heading_1}>
          Select type
        </Text>

        <View style={styles.imageSelectContainer}>
          {renderPhotoTypes()}
        </View>
      </ScrollView>);
  }
}

You can do something like this

  Details = [
        {
          type: "Party",
          image: require("../../../images/icons/photographer/Party.png")
        },
        {
          type: "Wedding",
          image: require("../../../images/icons/photographer/Wedding.png")
        },
        {
          type: "Architecture",
          image: require("../../../images/icons/photographer/Arhitecture.png")
        },
        {
          type: "Christening",
          image: require("../../../images/icons/photographer/Christening.png")
        }
  ];

  render() {
    let renderPhotoTypes = () => {
      let type = [];

      this.Details.map( ( item )=> {
        type.push(
          <View style={styles.imageSelectItem} key={item.type}>
            <TouchableWithoutFeedback>
              <View>
                <View style={styles.imageContainer}>
                  <Image style={styles.image} source={item.image}/>
                </View>
                <Text style={styles.text}>{item.type}</Text>
              </View>
            </TouchableWithoutFeedback>
          </View>
        );
      } );

      return type;
    };
