Here's a handle little Javascript function that'll let you rotate a set of DIVs as needed, e.g. to rotate a series of images for a slideshow. It uses Script.aculo.us to do a very simple looking yet quite appealing slide in/out. You'll need to load the prototype.js file and Script.aculo.us' effects.js file before running the code. One thing to note is that you can use any object to do this - DIVs, IMGs, etc, just assign the IDs accordingly, which is useful if you need to rotate entire code blocks and not just individual images. Enjoy!

The Apache web server, or more correctly Apache HTTP Server, is a wonderful program for serving web pages to the world. It can be a bit tricky to set up, however, especially if you want to run it on Windows as many of the configuration examples you'll find online are for UNIX rather than Windows.
