Installing icons

I have a zip file full of icons that I want to use (LINK). Since replacing the HDD icons etc are such a pain in the ass to do individually, is there a way that I can put them into one pack and use StyleXP to replace them all, saving me a ton of time and work?

yeah.. get icon packager and do it one by one on there...

Or use icon packager and download a package that's already made up.
Other than that you'd have to do it manually afaik.
