Crop multiple images to match them up in Photoshop?

Question

I have multiple partial screen shots of the same window. But since I created each of them at different times and since the I manually chose the select-area each time, the images don't line up.

I want to, for example, be able to open up one of the images in any "image preview" program and scroll through the images without them "jumping" left/right/up/down because of my inconsistent screen captures.

So, what's the quickest way to get the images to match up?

More: The images all are mostly identical, with just a few parts changing from image to image. I need them all to match up so that when I look through them, the changed parts are obvious and so I don't get nauseated with all the jumping.

To get your images into Photoshop layers, open Bridge, select the images you want and go to Tools>Photoshop>Load into Photoshop Layers.

Choose Edit > Auto-Align Layers and select Auto as the alignment option. If Auto does not create good registration of your layers, try the Reposition option.

Use the crop tool to crop all the layers at once.

Now, go to File>Scripts>Export Layers to files...

I'm not sure I entirely understand the workflow you're going for here but ...

1. Pick any one of the screen shots and open it in P'shop.
2. Crop it to the minimum area that will accomodate all the screen caps.
3. Drop all the other shots onto a layer in that doc.
4. Use transparency to get them to overlay just so.
5. If you want them in separate files, export each layer so they are all on the same canvas size.
