Seems like the path to image is broken, try to solve it by import image in the head of the file and add image path to your <img> element

import React, { Component } from 'react';
import logo from './logo.png';     // <-- import image here

class test extends Component {
    render() {
        return (
            <>
                <img src={logo} /> // <-- add image path here
            </>
        );
    }
}

export default test;

docs for adding images to your react app https://create-react-app.dev/docs/adding-images-fonts-and-files/

you must import that image and set width and height for that image

import image1 from "./1.jpg";
