Here's how to change your icons...

Go the the icon you want to use (Some of the .icns files have no image - ignore these) select the icon you want to use and press "Apple - C" (Copy). Then go to the file/folder which you wan to apply the icon to. "ctrl - click" (Or right click) on this file/folder, a menu should pop up. Select the "Get Info" part of the menu. Now a window should open with the icon being used and the name of the file/folder at the top. Select the icon being used and then press "Apple - V" (Paste) the icon should change to the one you copied. For some files you have to repeat the "ctrl - V" two or three times to make it happen (I think this is a bit of an Apple glitch).

One way to know that it is not going to work at all is if the icon changes to an icon that looks like a file with the letters ICNS in it. Then you know you need to start the whole process again.

Hope this helps
