CandyBar will do this. You can also manually change the icon using Photoshop and then replace it. Open up a Finder window and browse to your Applications folder, then to iChat. Right click on it and select 'Show Package Contents'. Then go to Contents/Resources/iChat.icns. If you edit that and replace it, it will display as the icon on your Dock.
hello shado, yes i tried that before. I went into package contents, changed the color of the chat.ins manually. Restared my comp and nothin changed. When i go back into package contents and click on the chat.ins , under preview the new color is shown but no changes take effect. The icon is still the default blue color? I have no idea why it wont change........it works for changing the dock color manually but not the ichat icon.....
I will try candybar now.......
if you have anymore suggestions that would be cool
thanks
The only other thing I would try would be the following: create a new ichat.icns file from a picture you want as the icon (ie altered color or w/e). You can use img2icns to change a pic into an .icns file. After you create that, replace the original ichat.icns file. Then remove the ichat icon from the dock and drag the updated one from your apps folder onto the Dock.
