In Photoshop, an easy way to crop an image to exactly the same size and resolution as another image is to open both, select the Crop tool, activate the image that has the size you like, and then click the Front Image button in the Options Bar.
When you click on your second image and drag with the Crop tool, the cropping rectangle will be constrained to the same dimensions as the first image. When you press the Return key, the second image will resize to the same resolution and size as the first image.
