You can change the image on click of the button, if you create a method changeImage
changeImage = () => {
this.setState({
loading: true,
});
this.getImage();
};
Live Demo
and call the getImage method in it
getImage() {
const apiURL = "https://api.giphy.com/v1/gifs/random";
const apiKEY = "bi3FFnNepwMz5HlDYwCfvyhXQLGrvVtL";
axios(`${apiURL}?api_key=${apiKEY}`).then((response) => {
this.setState({
giphy: response.data.data.images.fixed_height.url,
loading: false,
});
});
}

ComponentDidMount() only runs once in general, so it's not a good place to put your image loading logic. You should place your logic inside an onClick handler:
<button onClick={changeImage} className="mt-5 py-3 btn generate-btn">Get Random Cat Images</button>
which then calls the function suggested by @decpk
