I'd like to design a set of custom folder icons for Snow Leopard, much like the special folder icons that exists for the Home, Movies, Library etc. folders. For this, I want to use the vanilla folder icon and add some imagery. I use Icon Composer, so I need the standard folder icon template pictures for 512x512, 256x256, 128x128, 32x32 and 16x16. I think there are three different templates: one for 16x16, one for 32x32, and one for the larger ones. Does anyone know where I can find these pictures?
