adding an action

i downloaded an action to remove a color problem from my Nikon d1 digital camera, but i'm unsure how to add the action to my photoshop 5.5.
How is this done?
thanks

1st, make sure the action is for the version you are using.

Then, just put it under your Adobe\Photoshop 6.0\Presets\Photoshop Actions folder.

Then, if you haven't done so already, make sure PS is closed. Then re-open it, click Window-->Show Actions

Then, there is a little black arrow on the top right of the actions window. Click that and load your action you downloaded.

I'm running 6.0, so this may be a little different, but should give you a general idea.
