Photoshop 6.x and 7.x users:
- Download the CorrectPNG.atn action set
- Assuming a default installation (on a PC), put the action into:
C:\Program Files\Adobe\Photoshop X.0\Presets\Photoshop Actions - From the Actions palette menu (>), select CorrectPNG.atn (which should appear near the bottom of the menu, in alphabetical order)
Note: If the action does not appear in the palette menu, choose Load Actions; navigate to the appropriate path (from step 2, above) and select CorrectPNG.atn
