Well, it goes like this:

You have the files:
mod.dm
pic1.tga
pic2.tga
pic3.tga
pic4.tga

These are in 'mods' folder, that is a subfolder of 'Dominions 3'. This means that when you go to 'Dominions 3', you see a folder called 'mods' in there. Now, create a new folder in 'mods'. Call this 'stickmen'. Move the pictures in to the 'stickmen' folder.

Another way to put it:
pictures start here:
\Dominions 3\mods

pictures go here:
\Dominions 3\mods\stickmen

After you have done this, select 'stickmen' and 'mod.dm' and make a zip out of those two.
