An HTML image button is a clickable element in a web page that uses an image as its visual button, instead of the typical text-based button. It combines the functionality of a button with the visual appeal of an image. When a user clicks or interacts with the image button, it triggers a specific action just like a regular HTML button element.

To create an HTML image button, you can use the <input> element with the type attribute set to "image" or the <button> element with an <img> element inside it. Here are examples of both methods:

Option 1: <input>

<form method="post">
  <input type="image" src="image.png" alt="Submit">
</form>

Option 1: <button>

<button type="submit">
  <img src="image.png" alt="Submit">
</button>
