Hi yisong,
I think you can copy/paste the second image, move it around on top of the
first, and then use the paste control menu to choose the way the merge will
occur.
Alternatively, transform the first image to a 2-image stack, paste the other
image on the blank slice, and then use a projection with a suitable mode, or
a stack to rgb method, to get an overlay.
