I had the need to programmatically add an image to the DOM, in other words to an HTML page, dynamically.

To do that, I created an img element using the createElement method of the Document object:

const image = document.createElement('img')


Then I set the src attribute of the image:

image.src  = '/picture.png'


(You can use a relative or an absolute URL, just as you’d use in a normal HTML img tag)

Then I identified the container I wanted to append the image to, and I called the appendChild() method on it:

document.querySelector('.container').appendChild(image)
