How to change an image every 15 seconds in HTML - html

Question

I have an image in my HTML page, and I would like it to change to a different image every 15 seconds.
<img src="img/img 1.jpg" alt="image">
In my local folder img, I have two images which are img 1.jpg and img 2.jpg. How do I change the img 1.jpg to img 2.jpg after 15 seconds?

Answer 1

Try it:
$(document).ready(function(){
var img = 0;
var slides = new Array();
while (img < 5) {
img++;
// put your image src in sequence
var src = 'assets/images/earth/Sequence' + img + '.jpg';
slides.push(src);
}
var index = 0,timer = 0;
showNextSlide();
timer = setInterval(showNextSlide, 15000);
function showNextSlide() {
if (index >= slides.length) {
index = 0;
}
document.getElementById('earth').src = slides[index++];
}
});

Try this (pure JS)
var myArray = ['img1', 'img2', 'img3', 'img4', 'img5', 'img6']
var count = 0;
setInterval(function() {
//use this below line if you want random images
//var rand = myArray[Math.floor(Math.random() * myArray.length)];
if (count >= myArray.length) count = 0; // if it is last image then show the first image.
// use this below line if you want images in order.
var rand = myArray[count];
document.getElementById('img').src = rand;
document.getElementById('img').alt = rand; // use 'alt' to display the image name if image is not found
count++;
}, 1000); // 1000 = 1 second
<img src="img/img 1.jpg" alt="image" id='img' />

To do this, you're going to need some Javascript to change the image. Here is a link to a popular website for help with Javascript, HTML, CSS, and a whole lot more. What you'll want to be looking at specifically though, is the setInterval() function on this page: http://www.w3schools.com/js/js_timing.asp
If you don't know Javascript at all, it is also not a bad place to start learning! If that's all you need it for though, you'll need very little Javascript at all.

Firstly include jQuery library in your page.
Then use this script:
$(document).ready(function() {
setInterval(function(){
_path = $('img').attr('src');
_img_id = _path.replace('img/img', '');
_img_id = _img_id.replace('.jpg', '');
_img_id++;
if (_img_id == 3) {
_img_id = 1;
};
$('img').attr('src', 'img/img' + _img_id + '.jpg');
}, 15000);
});
