Python Gimp plugin to compare multi-spectral imaging images

When you have many images of the same subjects in different spectral bands some times you want to compare them. In this case the simple things to do is to juxtapose them showing local differences with a marker (an arrow or a circle) that indicates what is visible in one spectral band and not in the other. That's could be a quite tedious process, I have developed a Python Gimp plug-in to perform this task quickly. Basically you can load the images as different layers and juxtapose them. Furthermore you can add a transparent layer that can be duplicated over the others layer, so you can put in it markers that will be automatically superimposed over the same area in the others layer.  This video shows how it works.
