Readmes in general do serve a purpose, and should be read first.
The readmes of the Combat and Components packs have lines like this in them:
To install this imagemod, copy all the contained files into your ".../SE4/Pictures/components" directory.
Replace "components.bmp" with "Newcomponents.bmp". All of the original SE4 images are contained
in the new BMP, so all other mods and saved games will not be affected.
The facilities and planets packs need to be handled in the same way. It seems as if their readmes do not explicitly state this, and I was not aware of it. I apologize for the confusion. It will be fixed.
My mirror at least is now updated to include these instructions on the download page.
