It depends....
If the images are consecutive photos of the same scenes taken hand-held, the non-obvious difference it that the camera axis likely rotated a bit between the two (in addition to the camera position no being exactly, the same). There is no simple transformation in Gimp to compensate for this, panorama software such as Hugin do have this kind of functionality built-in (image stacking).
If the image are different anyway (the face of two different people), you can make the top temporarily partially transparent, and use the Unified transform tool to scale/rotate the top image to match the other one.
