If your page url contains multiple / then in src go back / count minus 1 times.

For example page url http://localhost:3000/play/game/ then src url must be ../your-image-folder/image-name. And your your-image-folder must be in public folder.

I create my app with create-react-app and I use require instruction if I want to change dynamically my image src:

export const MyComponent = () => {
  const [myImg, setMyImg] = useState(require('./path/to/my/img'));

  const handleClick = () => {
    setMyImg(require('./path/to/other/img'));
  }

  return (
    <div>
      <img src={myImg} alt='myImg' />
      <button onClick={handleClick}>Click me!<button/>
    <div>
  )
}

Place the logo in your public folder under e.g. public/img/logo.png and then refer to the public folder as %PUBLIC_URL%:

<img src="%PUBLIC_URL%/img/logo.png"/>

The use of %PUBLIC_URL% in the above will be replaced with the URL of the public folder during the build. Only files inside the public folder can be referenced from the HTML.

Unlike "/img/logo.png" or "logo.png", "%PUBLIC_URL%/img/logo.png" will work correctly both with client-side routing and a non-root public URL. Learn how to configure a non-root public URL by running npm run build.

A friend showed me how to do this as follows:

"./" works when the file requesting the image (e.g., "example.js") is on the same level within the folder tree structure as the folder "images".

I have used it this way and it worked perfectly

import Product from "../../images/product-icon.png";
import { Icon } from "@material-ui/core";

<Icon>
    <img src={Product} style={{ width: "21px", height: "24px" }} />
</Icon>

Import Images in your component

import RecentProjectImage_3 from '../../asset/image/recent-projects/latest_news_3.jpg'

And call the image name on image src={RecentProjectImage_3} as a object

 <Img src={RecentProjectImage_3} alt="" />

Adding file-loader npm to webpack.config.js per its official usage instruction like so:

config.module.rules.push(
    {
        test: /\.(png|jpg|gif)$/,
        use: [
            {
                loader: 'file-loader',
                options: {}
            }
        ]
    }
);

worked for me.

Some older answers din't work, others are good but won't explain the theme, in summary:

If image is in 'public' directory

Example: \public\charts\a.png

In html:

<img id="imglogo" src="/charts/logo.svg" />

In JavaScript:

Create image to new img, dynamically:

var img1 = document.createElement("img");  
img1.src = 'charts/a.png';  

Set image to existing img with id as 'img1', dynamically:

document.getElementById('img1').src = 'charts/a.png';

If image is in 'src' directory:

Example: \src\logo.svg

In JavaScript:

import logo from './logo.svg';  
img1.src = logo;  

In jsx:

<img src={logo} /> 

If the image is placed inside the 'src' folder, use the following:

<img src={require('../logo.png')} alt="logo" className="brand-logo"/>

1. Make an images folder inside src(/src/images) And keep your image in it. Then import this image in your component(use your relative path). Like below-

   import imageSrc from './images/image-name.jpg';

   And then in your component.

   <img title="my-img" src={imageSrc} alt="my-img" />

2. Another way is to keep images in public folder and import them using relative path. For this make an image folder in public folder and keep your image in it. And then in your component use it like below.

   <img title="my-img" src='/images/my-image.jpg' alt="my-img" />

   Both method work but first one is recommended because its cleaner way and images are handled by webpack during build time.

With create-react-app there is public folder (with index.html...). If you place your "myImage.png" there, say under img sub-folder, then you can access them through:

<img src={window.location.origin + '/img/myImage.png'} />

If you used create-react-app to create your project then your public folder is accessible. So you need to add your image folder inside the public folder.

public/images/

<img src="/images/logo.png" />

In create-react-app relative paths for images don't seem to work. Instead, you can import an image:

import logo from './logo.png' // relative path to image 

class Nav extends Component { 
    render() { 
        return ( 
            <img src={logo} alt={"logo"}/> 
        )  
    }
}
