HTML | DOM Image Object
  • Last Updated : 31 Jan, 2019

The Image Object in HTML DOM is used to represent the HTML < image > element.
This tag is used to set or get the properties of < image > element. This element can be accessed by using getElementById() method.

Syntax:

document.getElementById("Image_ID");

This Image_ID is assigned to HTML < image > element.

Example-1:




<!DOCTYPE html>
<html>
  
<head>
    <base id="Geek_Base"
          href="https://www.geeksforgeeks.org">
    
    <title>
        HTML | DOM Image Object
    </title>
</head>
  
<body style="text-align:center;">
  
    <h1 style="color:green;">  
            GeeksForGeeks  
        </h1>
  
    <h2>HTML | DOM Image Object</h2>
  
    <button onclick="myGeeks()">
        Click
    </button>
    <h4><p id="Geek_p" 
           style="color:green">
      </p></h4>
  
    <script>
        function myGeeks() {
  
            //   Creating IMG object.
            var x = document.createElement("IMG");
            
            x.setAttribute("src", 
            
            x.setAttribute("width", "304");
            x.setAttribute("height", "228");
            x.setAttribute("alt", "GFG_Logo");
            document.body.appendChild(x);
