This has been done many times using pure javascript and html.

Changing the images in such slideshows means that the javascript and
html need to be re-written.
 

However, the slideshow you are about to see has been dynamically
constructed using perl and the glob command.

In this way, the images can be changed and the slideshow updated
without the need to re-write the javascript or html.

Which means less hassle, quicker response times for getting changes 
onto live sites and lower costs.
