My first question

I've just used a falling snow tut over a color photo, in ImageReady via PS CS2...yet when I go to view it before saving it, the icon shows black and white!? I have not run into this problem before, and I'm not sure what's going on or how to fix it. Any ideas?

***EDIT*** I haven't figured out the issue with using the gif or psd, but I did get it to work by saving each layer as it's own picture, and then layering it myself. Thanks everyone! MUAH
