  • Show only the first image and hide the others;
  • Place a “current” class on the list-item;
  • Only exucute the function once when it has a current status.

That’s it? Yep… it’s that simple!

jQuery code


$(function() {
   var imgWrapper = $('.slideshow > img');
   // only show the first image, hide the rest
   $('ul.recentlist li a').click(function () {
    // check if this item doesn't have class "current"
    // if it has class "current" it must not execute the script again
    if (this.className.indexOf('current') == -1){
     $('ul.recentlist li a').removeClass('current');
    return false;


We are making sure that when a list-item has the “current” class, the script won’t be executed again.

CSS code


.slideshow { 
  position: relative; 
  background: #fafafa; 
  width: 403px; 
  height: 240px; 
  border: 1px solid #e5e5e5; 
  margin-bottom: 20px; 
  .slideshow img { 
  position: absolute; 
  top: 3px; 
  left: 3px; 
  z-index: 10; 
  background: #fff; 
  ul.recentlist { 
  position: absolute; 
  bottom: 12px; 
  right: 4px; 
  list-style: none; 
  z-index: 20; 
  ul.recentlist li { display: inline; }
  ul.recentlist li a, ul.recentlist li a:visited { 
  display: block; 
  float: left; 
  background: #e5e5e5; 
  padding: 4px 8px; 
  margin-right: 1px; 
  color: #000; 
  text-decoration: none; 
  cursor: pointer; 
  ul.recentlist li a:hover, ul.recentlist li a:visited:hover { 
  background: #666; color: #fff; 
  ul.recentlist li a.current { 
  background: #f00; 
  color: #fff; 


In this example the unordered list is absolute, that way you can easily position the list-items above the images.

HTML code


<div class="slideshow">
   <ul class="recentlist">
    <li><a class="current" href="#slide1">1</a></li>

    <li><a href="#slide2">2</a></li>
    <li><a href="#slide3">3</a></li>

   <img id="slide1" src="slide-1.gif" alt="Image 1 slideshow" />
   <img id="slide2" src="slide-2.gif" alt="Image 2 slideshow" />
   <img id="slide3" src="slide-3.gif" alt="Image 3 slideshow" />
