Here are some Dogcow Button icons that can be used in World of Warcraft v1.7 on macros.
Create a folder named ‘Icons’ in your ‘Interface’ folder. Do this while WoW is quit, reloading the UI after placing them to install does not work well.
You can try them out right now if you have the Test Client for v1.7 installed.
