Stack Action image

Can somebody link me to a tutorial to stack a group of images. I want to stack several action images of diving into a pool.

Do you mean stack s in create an animation or stack as in "grouping" them in software? What software are you using to edit/organize your photos?

I don't know of a specific tutorial to recommend as I've never done it but if you want to do what I think you do then the term you want to put into Google (or any search engine but lets face it, they're all rubbish except Google) would be, "multiplicity photoshop tutorial". Some of them will give you just multiple people in a room but they should help a bit but there must be one that gives you axactly what you're after.

I guess you would call it an animation. I have some shots of someone diving and I want to overlay or stack them so that the diver appears several times on the image at different positions. Using Photoshop CS3.

That would be a composite.

Layer Masks

Layer Masks - What the Thumbnails mean

They're also great for PPing just a part of an image:

One approach to this is to have several shots in sequence that you blend together, so that one person is replicated in several positions -- not hard if you blend the scenes as layers together and brush them into each other.

This thread shows some examples and tosses in some tutorials:
