If you are a photographer, you sometimes need to switch between the same images while maintaining the zoom area. There is no such possibility in the standard explorer. But it is in third parties software.
For example, Pictureflect Photo Viewer makes this very easy. Just open your image folder and zoom in on the area you want.
And in the Zoom menu, select which area you want to capture. You can choose any combination of layout, crop, zoom, pan, and viewport.
