Why is axios returning the previous images from flickr even if the tags are logged correctly.

import React, { Component } from 'react'; import ImageList from './FetchData'; import axios from 'axios'; import apiKey from '../config'; import Image from './Image';

class PhotoContainer extends Component { constructor(props) { super(props); this.state = { images: [], loading: true }; }

componentDidMount = () => {
    this.performSearch(this.props.tag);
};

shouldComponentUpdate = nextProps => {
    if (this.props.tag === nextProps.tag) {
        return false;
    } else {
        console.log(nextProps.tag);
        this.performSearch(nextProps.tag);
        return true;
    }
};

performSearch = tag => {
    console.log('tag' + tag);
    axios
        .get(
            `https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=${apiKey}&tags=${tag}&per_page=8&format=json&nojsoncallback=1`
        )
        .then(response => {
            //  console.log(response.data);
            this.setState({
                images: response.data.photos.photo,
                loading: false
            });
        })
        .catch(error => {
            console.log('Error fetching and parsing data', error);
        });
    return;
};

render() {
    return (
        <div className="photo-container">
            <h2>{this.props.tag}</h2>
            <ul>
                {this.state.loading ? (
                    <p>loading</p>
                ) : (
                    this.state.images.map(image => (
                        <Image
                            url={`https://farm${image.farm}.staticflickr.com/${
                                image.server
                            }/${image.id}_${image.secret}.jpg`}
                            title={image.title}
                            key={image.id}
                        />
                    ))
                )}

                <li className="not-found">
                    <h3>No Results Found</h3>
                    <p>You search did not return any results. Please try again.</p>
                </li>
            </ul>
        </div>
    );
}

}

export default PhotoContainer;
