How can JavaScript be utilized to ensure that an image on a webpage updates periodically?

To ensure that an image on a webpage updates periodically, JavaScript can be utilized to reload the image at regular intervals using the setInterval() function. By setting a timer to refresh the image source, the webpage will automatically update the image without requiring a manual reload. ```javascript // Set the interval in milliseconds (e.g. 5000ms = 5 seconds) setInterval(function() { document.getElementById('imageID').src = 'image.jpg?' + new Date().getTime(); }, 5000); ```
