Ok, here goes.
there are three directories called
at2. One of them
at2, the next
at2BIG, and then
at2SMALL. These are core directories for graphics for the upgrade done to AT when it went Gold. That is everything you see on the map, including Flags and such, in the ANewDawn games. Also Officer faces.
One of them is called BIG, because that one contains graphics relevant for the zoom in mode, and the other one is called SMALL because that one contains graphics relevant for the zoom out mode. This BIG, SMALL and no suffix of folders, is general in connection with graphics. If you make your own scenario, from scratch, and a graphic that is supposed to be in one of those folders is not there, then it will be scaled up and down, and put into a folder with the relevant suffix.
In My version of the game, there is also an
alt group of graphic directories. These are for alternative graphics, for landscapes. It again has a BIG and SMALL version. I am unsure if this comes with the game or not.
The there are the
Default folders. These contain the graphics for the original AT. So everything you'd find in the stock version scenarios of that type.
Newdawnmodgraphics folders contain the TO&E graphics for ANewDawn random games, as well as the special landscape graphics, that can be put over existing landscapes, via the LT part of the editor. Mines for instance.
Phoenixmodgraphics folders contain the TO&E graphics that are used in Phoenix. Again in various sizes. They also in the same list of graphics include special landscape graphics
systemgraphics folders contain the graphics that make up the GUI.
NONE of these should ever be touched, or added to or otherwise tampered with. The reason mainly being that updates will overwrite these, should there be updates in them, and... other players will not get files in these folders with the scenarios that are packaged. So you would get error messages when starting up a game, about missing graphics.
The correct way to make a scenario or graphics mod, is to make a folder, that you call something or other. There will be no need to make the SMALL and BIG folders to begin with, but, if you want to have cooler looking zoomed in graphics, then you should make BIG graphics too, and put a version of them in there, with the appropriate dimensions. This is where you deposit your own graphics, and these will be packed with the ATZIP function.
If you then want to use for instance the NATO counters of another folder, you direct the link in the setng menu to those. You can even make your own Systemgraphics folder in it, and get special graphics for your own PC. (I have yet to see these being packed by the ATZIP).

In the scenario itself, you can direct graphics to any folder you wish.
To get graphics for cards working, you need to have a Event Graphic. These too can be linked to in the Setng part of the editor. You just select the EventPics menu from the Property sheets:

The pictures can be jpg, gif, bmp and png. I don't believe any other formats are allowed. These event pics have numbers, which are then used in the card and in messages in the event editor too.
