Snow?

Hello everyone.

I recently downloaded the "Winter Wonderland" action.

I know how actions work, or so I thought, because I can’t seem to get this one to work. I downloaded it, loaded it into photoshop, and "played" it from the actions menu. It runs ok I assume because I don’t see any errors, and at the end I have a static picture of the snow on top of my document. But now what?

I saved my image as jpg and gif, and looked at them both, and there’s no animation. What am I missing? Please help.

Thanks in advance.
