Hi KEVSWS6,
It simply puts tracking programs on your computer so they can see what sites you visit and adds to your cookies.
I use a free program called Ad-aware 6.0 and use it to scan my computer every time my pop up blocker alerts. Usually when pop ups adds are detected they are adding spy-ware to your computer.
Sorry you're taking the pic's down, as it is nice to see others and their projects.
