To share any image in React Native you are right you need to use the Share from react-native library itself, and you were wondering what is needed for an image, the answer it's really simple, you just need to use a Base64 image.

Check it out a working snack: snack.expo.io/@abranhe/share-image

Wrap the code:

import * as React from 'react';
import {
  Text,
  View,
  StyleSheet,
  Image,
  Share,
  TouchableOpacity,
} from 'react-native';

export default class App extends React.Component {
  state = {
      cat: 'data:image/jpeg;base64,some-encoded-stuff;
  };

  handleSharePress = () => {
    Share.share({
      title: 'Share',
      message: 'My amazing cat 😻',
      url: this.state.cat,
    });
  };

  render() {
    return (
      <View style={styles.container}>
        <Image source={{ uri: this.state.cat }} style={styles.img} />
        <TouchableOpacity onPress={this.handleSharePress}>
          <Text>Share Image</Text>
        </TouchableOpacity>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'space-around',
    alignItems: 'center',
  },
  img: {
    width: 200,
    height: 300,
  },
});

If you want to try something else, probably complex, I recommend to check out the react-native-share library from the React Native Community.

import Icon from 'react-native-vector-icons/Feather';
import Share from 'react-native-share';
import RNFetchBlob from 'rn-fetch-blob';
import React, {Component} from 'react';

const fs = RNFetchBlob.fs;
class ProductDetail extends Component {
  constructor(props) {
    super(props);
    this.state = {};
  }

shareTheProductDetails(imagesPath) {
    let {productDetails} = this.state;
    let imagePath = null;
    RNFetchBlob.config({
      fileCache: true,
    })
      .fetch('GET', imagesPath.image)
      // the image is now dowloaded to device's storage
      .then((resp) => {
        // the image path you can use it directly with Image component
        imagePath = resp.path();
        return resp.readFile('base64');
      })
      .then((base64Data) => {
        // here's base64 encoded image
        var imageUrl = 'data:image/png;base64,' + base64Data;
        let shareImage = {
          title: productDetails.product_name, //string
          message:
            'Description ' +
            productDetails.product_description +
            ' http://beparr.com/', //string
          url: imageUrl,
          // urls: [imageUrl, imageUrl], // eg.'http://img.gemejo.com/product/8c/099/cf53b3a6008136ef0882197d5f5.jpg',
        };
        Share.open(shareImage)
          .then((res) => {
            console.log(res);
          })
          .catch((err) => {
            err && console.log(err);
          });
        // remove the file from storage
        return fs.unlink(imagePath);
      });
  }

render() {
return (
<TouchableOpacity
style={{
  borderWidth: 0,
  left:(5),
  top:(2),
}}
onPress={() =>
  this.shareTheProductDetails(images)
}>
<Icon
   style={{
     left: moderateScale(10),
   }}
  name="share-2"
  color={colors.colorBlack}
  size={(20)}
/>
</TouchableOpacity>
)}
}
