I have a 13'' White MacBook with Mac OS X Tiger. Recently, I downloaded a set of Mac icons from an icons website. I had already-existing custom icons and was familiar with the process of changing them (Get info, copy, paste, etc.). After downloading the new set of icons (which were in .icns format), i found that when I went through the process of changing them, they did not appear as the pictures I wanted on my dock, but instead appeared as the generic .icns icon (The page icon that does not show the actual image and says ICNS with the tiny 'preview' image above it). I don't know how to make these new icons visible my dock and I would appreciate any advice you can give. I'm sure this question has been asked several times in the past and I'm so sorry for being, most likely, the millionth person to have this problem.
