I have the following codes which also works but they re influencing some of my other codes. I don't know why.

Can someone help me with another solution.

I am not a programmer so please explain things easy. thanks

What I have tried:

Html

<script type="text/javascript">
var picPaths = ['iphone1.png','iphone2.png','iphone3.png'];
var curPic = -1;
//preload the images for smooth animation
var imgO = new Array();
for(i=0; i < picPaths.length; i++) {
imgO[i] = new Image();
imgO[i].src = picPaths[i];
}

function swapImage() {
curPic = (++curPic > picPaths.length-1)? 0 : curPic;
imgCont.src = imgO[curPic].src;
setTimeout(swapImage,2000);
}

window.onload=function() {
imgCont = document.getElementById('imgBanner');
swapImage();
}

</script>

body

CSS

#imgBanner {
position:absolute;
right: 80px;
top:836px;
z-index:9999;
padding: 0;
}

You can utilize javascript's in-built method setInterval to accomplish this.

Here's a quick solution that I can think of,

Let me know if you 've any questions.

// Initialize images in an array
var picPaths = ['iphone1.png','iphone2.png','iphone3.png'];
// An index to track the contender image 
var imageIndex = 0;
var bannerImage; 

// An event callback for starting the interval
function startInterval() {
 setInterval(displayNextImage, 3000);
}

function displayNextImage() {
  bannerImage.src = picPaths[imageIndex];
  if(imageIndex === (picPaths.length-1)) {
    imageIndex = 0;
  }
  else {
    imageIndex = imageIndex + 1; // It can be replaced with imageIndex ++  
  }
}

window.onload=function() {
 bannerImage = document.getElementById('imgBanner');
 startInterval();
}
