I just downloaded ICONOGRAPHER, from (if I remember correctly, either Versiontracker or CNET's download.com)... However, when I read through the tutorial I have noticed that it mentions that icons often come with a mask layer to help instruct which part of the square 128 pixel by 128 pixel would be transparent so the background can be seen. Now, when it comes to customizing icons I'm used to simply going into the FILE>INFO section in OS9 and cutting and pasting from one file to another. But in OSX if I do that with FILE>SHOW INFO, I have noticed that the transparent parts of the icon itself becomes white when pasted into the new icon. I'm figuring at this point that there has to be a better way, but I simply don't know how. If anyone would mind explaining how one goes about doing this, I would sure appreciate it. Thanks!
