I have two existing images that are identical in size and I would like to combine them, so that I can see a "faded" version of one image on top of the other.
In other words, I want to make "Image A" semi-transparent / opaque and place it on top of "Image B", so that I can see "Image B" and see a faded version of "Image A" (over the top of "Image B").
I am using The GIMP 2.10.30.
