Correct path for img on React.js

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"}/> 
        )  
    }
}

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" />


You're using a relative url, which is relative to the current url, not the file system. You could resolve this by using absolute urls

<img src ="http://localhost:3000/details/img/myImage.png" />

But that's not great for when you deploy to www.my-domain.bike, or any other site. Better would be to use a url relative to the root directory of the site

<img src="/details/img/myImage.png" />


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'} />

  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.


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

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

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} />
