try using

import mainLogo from'./logoWhite.png';

//then in the render function of Jsx insert the mainLogo variable

class NavBar extends Component {
  render() {
    return (
      <nav className="nav" style={nbStyle}>
        <div className="container">
          //right below here
          <img  src={mainLogo} style={nbStyle.logo} alt="fireSpot"/>
        </div>
      </nav>
    );
  }
}

You can use require as well to render images like

//then in the render function of Jsx insert the mainLogo variable

class NavBar extends Component {
  render() {
    return (
      <nav className="nav" style={nbStyle}>
        <div className="container">
          //right below here
          <img src={require('./logoWhite.png')} style={nbStyle.logo} alt="fireSpot"/>
        </div>
      </nav>
    );
  }
}

If the images are inside the src/assets folder you can use require with the correct path in the require statement,

var Diamond = require('../../assets/linux_logo.jpg');

 export class ItemCols extends Component {
    render(){
        return (
            <div>
                <section className="one-fourth" id="html">
                    <img src={Diamond} />
                </section>
            </div>
        )
    } 
}

There are few steps if we dont use "create-react-app",(webpack@5.23.0) first we should install file-loader as devDedepencie,next step is to add rule in webpack.config

{ test: /\.(png|jpe?g|gif)$/i, loader: 'file-loader', }

, then in our src directory we should make file called declarationFiles.d.ts(for example) and register modules inside

declare module '*.jpg'; declare module '*.png';

,then restart dev-server. After these steps we can import and use images like in code bellow

import React from 'react'; import image from './img1.png'; import './helloWorld.scss'; const HelloWorld = () => ( <>

React TypeScript Starter

); export default HelloWorld;

Works in typescript and also in javacript,just change extension from .ts to .js

Cheers.

I also had a similar requirement where I need to import .png images. I have stored these images in public folder. So the following approach worked for me.

<img src={process.env.PUBLIC_URL + './Images/image1.png'} alt="Image1"></img> 

In addition to the above I have tried using require as well and it also worked for me. I have included the images inside the Images folder in src directory.

<img src={require('./Images/image1.png')}  alt="Image1"/>

---

You can also try:

...
var imageName = require('relative_path_of_image_from_component_file');
...
...

class XYZ extends Component {
    render(){
        return(
            ...
            <img src={imageName.default} alt="something"/>
            ...
        )
    }
}
...

Note: Make sure Image is not outside the project root folder.

---

To dynamically import an image using a variable, you can use the following:

  const imageName = "myImage.png"
  const images = require.context('../images',true);
  const [imgUrl, setImgUrl] = useState('');

  useEffect(() => {
    if (images && imageName) {
      setImgUrl(
        images(`./${imageName}`).default
      );
    }
  }, [imageName,images]);

  ...

  <img src={imgUrl} />

---

Create a folder and name it as images.ts or images.js in your assets folder or anywhere you wish.

Export all images in a folder using the export {default as imageName} from 'route' statement.

export { default as image1 } from "assets/images/1.png";
export { default as image2 } from "assets/images/2.png";
export { default as image3 } from "assets/images/3.png";
export { default as image4 } from "assets/images/4.png";

then import images using the import {imageDefaultName} from 'route'

import {image1,image2,image3,image4} from 'assets/images'

<img src={image1} />
<img src={image2} />
<img src={image3} />
<img src={image4} />

OR

import * as images from 'assets/images'

<img src={images.image1} />
<img src={images.image2} />
<img src={images.image3} />
<img src={images.image4} />

---

import React, {Component} from 'react';
import imagename from './imagename.png'; //image is in the current folder where the App.js exits


class App extends React. Component{
    constructor(props){
     super(props)
     this.state={
      imagesrc=imagename // as it is imported
     }
   }

   render(){
       return (

        <ImageClass 
        src={this.state.imagesrc}
        />
       );
   }
}

class ImageClass extends React.Component{
    render(){
        return (

            <img src={this.props.src} height='200px' width='100px' />
        );
    }
}

export default App;

I used user5660307 answer. And also for server-side rendering using react and nodejs, you can add this in express server:

app.use(express.static("public"));

and in webpack.client.js:

module.exports = {
  entry: "./src/client/client.js",

  output: {
    filename: "bundle.js",
    path: path.resolve(__dirname, "public"),
  },

  module: {
    rules: [
      ...
      {
        loader: require.resolve("file-loader"),
        exclude: [/\.(js|mjs|jsx|ts|tsx)$/, /\.html$/, /\.json$/],
        options: {
          name: "static/media/[name].[hash:8].[ext]",
        },
      },
      {
        test: [/\.bmp$/, /\.gif$/, /\.jpe?g$/, /\.png$/],
        loader: require.resolve("url-loader"),
        options: {
          name: "static/media/[name].[hash:8].[ext]",
        },
      },
    ],
  },
};

---

Move the image(s) to /public/images folder. Add path in src as 'images/[filename]'

---

Simple way is using location.origin
it will return your domain
ex
http://localhost:8000
https://yourdomain.com

then concat with some string... Enjoy...

<img src={ location.origin+"/images/robot.svg"} alt="robot"/>

More images ?

var images =[
"img1.jpg",
"img2.png",
"img3.jpg",
]

images.map( (image,index) => (

  <img key={index} 
       src={ location.origin+"/images/"+image} 
       alt="robot"
  />
) )

---

Solved the problem, when moved the folder with the image in src folder. Then I turned to the image (project created through "create-react-app") let image = document.createElement("img"); image.src = require('../assets/police.png');
