Wheel configurator

Hello,

I was searching for a wheel configurator and I found this website:

http://www.hostilewheels.com/iconfigurators/

This is made with software from “iconfigurators”

But you have to pay for it…

Is there a script or something like this for free? So I can make my own car pictures ect… I only want to know the technolgy behind it…

So if someone knows something like this for free that I can work out that would be great.

Thanks in advance
