The best I can explain this:

You have a relatively small image with some transparent (empty) areas. Under this, a much larger image, which is only visible through the transparent areas of the top layer, and of course from around the sides of the top layer.

Now, you want to rotate the bottom layer a few degrees at a time, to create frames for an animated GIF.

The problem:

How do you completely eliminate the "overhang" of the large bottom layer from around the sides of the small top layer? The only part of the bottom layer I want visible is from the transparent areas of the top layer. Regarding this top layer, I don't want anything visible outside of it, even though the bottom layer is actually much larger.

How can this be done without tediously editing every single frame. (There could be HUNDREDS of them).

Any information would be greatly appreciated!

In imageready, make a duplicate of the rotating layer for each frame you want. Rotate each layer so that you have a different angle for each frame. Use the animation window to create new animation frames. In each frame, hide all the layers except the one you want to show during that frame, plus of course the non-moving layer. To get the center of the image, create a slice where you want to crop the animation. Set the slice's optimize settings to gif, and save optimized.

Maybe in CS2 there's a way to tween rotation, but I only have CS1 and it will only tween position, opacity, and effects.

edit: if you want to keep the white space outside instead of cropping, add a layer that's a white frame on top of all the rotated layers.

Make a document the size of the smaller image, place the larger image behind. Photoshop remembers the whole image. If you save a psd, you can move the larger image around and parts previosly outside the image bounds are again revealed, even after closing the file.

hope this helps
