Download either the production version or the development version of Cycle2.
In your web page:
<!-- include jQuery -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js"></script>
<!-- include Cycle2 -->
<script src="http://path/to/your/copy/of/jquery.cycle2.js"></script>
...
<!-- declare a slideshow -->
<div class="cycle-slideshow">
<img src="http://malsup.github.com/images/p1.jpg">
<img src="http://malsup.github.com/images/p2.jpg">
<img src="http://malsup.github.com/images/p3.jpg">
</div>
That's it! You don't need to write any script to initialize the slideshow, Cycle2 will auto-initialize if you use the class cycle-slideshow.
