HOWTO: add new mac icons

As stupid as it is, adding new icons in apple computer is unthinkable. I finally figured it out after about half of a day intensive surfing and it goes as follows:

1. Highlight the file on which icon you want to change, click "info". Info can be found by right clicking the file or it also can be found on top of finder.
2. Open the folder where the new icons are saved, highlight the desired icon then click "info".
3. Now you have both windows' info open like this:.
4. Last step is to copy the desired icon by doing command+c on the icon placed on the top side of info window, then do command+v on the the other info window (to be replaced icon). Notice the icons must be blue highlighted like this:
   

That's it!! you've made it... easy hah!! but again it was designed for grannies. You have to change every single icons you want manually and the other thing is, i don't know where the original icons are saved, so there's no way back. Maybe anyone can help me. It sucks. But i suppose, apple has the cutes icons from all OS engine, that it's not necessary to replace them.

If you still wanna try, then you can find the icons in apple's website. Good luck!!
