If you have some images still reloading after being cached, try to store them in the window object :

componentDidMount() {
    const imagesPreload = [image1, image2, image3];
    imagesPreload.forEach((image) => {
        const newImage = new Image();
        newImage.src = image;
        window[image] = newImage;
    });
}

(you don't need to call images from the window object)
