Fun tinkering with PHP

I have to say here that I'm more familiar with HTML than PHP. However, I wanted a script to randomly display a set of icons, so I dug around, found a script which displayed one image, and played around with it to get three images. It's klunky, but it does the job I want it to for the most part.

The idea on this whole thing was to do a portal for Wonki, my image archive (icons and wallpapers), and to display my rules (please comment, don't hotlink).

If you want to see what it looks like, it's here.
