Automatically align image layers
The Auto-Align Layers command can automatically align layers based on similar content in different layers, such as
corners and edges. You assign one layer as a reference layer, or let Photoshop automatically choose the reference layer.
Other layers are aligned to the reference layer so that matching content overlays itself.
