Hi,

How do I alter an existing image on the dock such as the Mail icon ??

You need to change the actual applications icon within your /Applications directory, and the next time you launch the program from the dock, the icon will update with the changes you made.

You need to change the image of the Apple Mail application icon itself.

If you've done that already, just drag Mail out of the Dock (poof) and then back in to refresh the icon. Often command-clicking the Dock icon will refresh it as well.

If you haven't changed the Mail app icon, command-click the icon in the Dock (or select Show in Finder from Mail's Dock menu). This will show the original app. Then while selected, you can Show Info and cut and paste a new icon into the icon spot on top.

However, some icons cannot be changed simply by cutting and pasting. I am not sure mail.app is one of them, but Omniweb is. If you see that pasting does not work, go to the application, right click and select 'Show contents'. Then look for the icon file, with the ending .icns Replace it with a new icon - which must also be a .icns file.
I also noticed that some icons change only after a logout and even after a restart (Yahoo messenger for example)
