Installation Automation is a class I wrote and uploaded at phpclasses.org. The main idea behind that class is to allow script writers create forms and allow easy installation of systems for the users downloading the systems.
The main intention of this post is not to promote the class (although this is what it is down as well as the main intention), but to speak of a little thing that you can do with it besides automating the installation process.
I included a second example of a slideshow you can do with it... although this is possible, I don't really recommend using this class for it. The main intention behind that slideshow demonstration is to show you that automating installation is only one thing you can do with this class.
The main reason behind this article was to tell you that the class's main intention was not for a slideshow... there are way better scripts for slideshow, although this may as well be the easiest way to accomplish this.
