I wanted to make a macro that would allow you to change large, inconsistently constructed, groups of images in the same way using the same macro. For example, I have 60 four channel images (Cyan, Blue, Green, Red) that I want to be three channel images (Green, Red, Blue), but the blue channel is supposed to be green, the red is supposed to be blue, and the green is supposed to be red. This should do that.
