                        var intervalId;

                        $('ul img').each(function () {
                                imageURLs.push($(this).attr('src'));

                                if (currentImageIndex == (imageURLs.length - 1)) {
                                        currentImageIndex = -1;

                                $(this).attr('disabled', 'disabled');
                                btnStop.removeAttr('disabled');

                });
        </script>
</body>
</html>
Steps:
  1. First, we are making a new array “imageURLs” in which we are storing the ‘src’ attribute values of all thumbnail images.
  2. Then we have created our function setImage(). In that, we are retrieving the src attribute of the current image that is displayed on the #mainImg. And then we are finding the index number of that in imageURLs array. If that current image index is matching the index of the last element, then we are deliberately setting the current image index to -1 so that when it will be increased by 1 it will have the index 0 i.e. the first element. And then we are setting the src attribute value of the main image element to the next indexed element of the array.
  3. In the “Start” button we’re attaching a click event handler to execute setInterval() method. And simultaneously we are disabling the “start” button and enabling the “stop” button
  4. In the “Stop” button we’re attaching a click event handler to execute clearInterval() method. And simultaneously we are disabling the “stop” button and enabling the “start” button.
Output:

Now run the above code and you will get the following output. Click on the Start button to start the Image slideshow and click on the stop button to stop the image slideshow.
