Given an HTML element and the task is to create an <img> element and append it to the document using JavaScript. In the following examples, when someone clicks on the button then the <img> element is created. We can replace the click event with any other JavaScript event.

Approach 1:

Create an empty img element using document.createElement() method.
Then set its attributes like (src, height, width, alt, title, etc).
Finally, insert it into the document.

Example: This example implements the above approach.

<!DOCTYPE HTML>
<html>
 
<head>
    <title>

    <h3>
        Click on the button to add image element
    </h3>
 
    <button onclick="GFG_Fun()">
        click here
    </button>
 
    <h2 id="result" style="color:green;"></h2>
 
    <script>
        let res = document.getElementById('result');
 
        function GFG_Fun() {
            let img = document.createElement('img');
            img.src =
'https://media.zambiatek.com/wp-content/uploads/20190529122828/bs21.png';
            document.getElementById('body').appendChild(img);
