Correct path for img on React.js


Question

I have some problem with my images on my react project. Indeed I always thought that relative path into src attribute was built on the files architecture

Here my files architecture:

components
    file1.jsx
    file2.jsx
    file3.jsx
container
img
js 
... 

However I realized that the path is built on the url. In one of my component (for example into file1.jsx) I have this:

localhost/details/2
<img src="../img/myImage.png" /> -> works

localhost/details/2/id
<img src="../img/myImage.png" /> -> doesn't work, images are not displayed

How is it possible to solve this problem? I want that in any form of routes handled by react-router, all images can be displayed with the same path.

Accepted Answer

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" />

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" />

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} />
