Well I didn't change that image mod 3 thingy, but added some more stuff after it since in the readme I have it says Image Mod Readme 3 Planets.

I still am totally confused as to the "3" part.

Perhaps you mean "Imagemod Planetpack, Version 3 or higher" ?

The imagemod is a collective term for the four separate packs of image files; Planets, Combat, Components and Facility.
Each pack has Version numbers from 1 to 20 or so, increasing with time as submissions are made.

Since images make for large downloads, the imagemod packs are designed to be placed over top of the original, unmodded files.
Thus, all mods can make use of the files at the same time; only one copy of them needs to be downloaded, and only one needs to remain on the user's harddrive.

Since the larger packs are up to 10 megs zipped, this is a major savings.

Modders such as yourself can use any of the images. You get free access to all of the great pictures, and it doesn't even increase the size of your mod. Most people won't even have to download the imagemod packs, since they will already have them.
