Photoshop CS3 Question

For the people that really know alot about photoshop. Do you know how to create a GIF using photoshop. Here is what i have done so far.
 
-Made 3 pictures to size (all on 3 layers)
-The used the "Animation" toolbar to then create a video where the 3 pictures fade in and out from each other.
 
So now i have this animation in the toolbar. And i go to save it with "saveas" and do it as a GIF. However when i do this is keeps converting the layers to 2d and saves it without any animation. How do i take my animation and make it into a GIF?
 
Basically im trying to make an avitar with animation. Thanks

never mind guys. I figured it out with a how to online. If anyone wants to know i can give alittle writeup on it. Its pretty easy if your used to dealing with timeline type animation
