How to make identical crops on multiple images?

[Bounty Hunter 23]

I have 15 screen captures.  I want to crop and resize them, then combine the results into an animated GIF.  How can I make sure I am getting the EXACT same area cropped from each image? The attached is a sample but is obviously to large and has extraneous screen contents that I don't want in the final version.

(Using Adobe PS CS6)

Load the screen catures into a stack. Photoshop's menu File>Scripts>Load Files into a Stack..., Crop the captured stack, Create a frame animatiion in the timelina panel]], use maks frame from layers, export save for webt your animated gif.
