Map Preview Extractor 
The Map Preview Extractor lets you extract the 256x256 Map Preview Image stored in maps made by Petroglyph's Forces of Corruption Map Editor  and save it as a TGA file.
Download To run, just unzip the archive to a location of your choice and start MapPreviewExtractor.exe.
Manual 
   Use the "Browse" button to select a Map file where you want to extract the preview from. You can also drag a map file 
   onto the application window or executable. Then hit "Extract Preview" and select a location to save the TGA file to.
  
  
    Important : After extracting, the preview image is REMOVED  from the original map file.
  
Base Layouts 
   This tool will make it possible to create fully functional Base Layouts in Galactic Conquest maps in
   Empire at War: Forces of Corruption. By removing the preview image from the map, the markers are enabled
   on the Base Layout screen in the game.
  
  
    Note that the extracted preview image can be used as background for the Base Layout: resize the extracted image to
    512x512 and save it in the Textures directory as a DX3 DDS file, with the same filename as the map.
  
64-bit update Petroglyph released an updated 64-bit-compatible version of the map editor . This version does NOT  save embedded texture previews in the map anymore. At all. So the map preview extractor doesn't work on map created with this updated version of the editor.
However, there is good news. The editor has a menu option "Tools > Generate Map Preview Image" which generates & saves the preview image to the location "..\Art\Textures\MapPreview\". This path is relative to the editor executable, not relative to the opened map.
So for instance, for the Steam version, you just have to ensure the folder "...\steamapps\common\Star Wars Empire at War\Art\Textures\MapPreview" exists, and whenever you execute that menu option, the previews will be saved there.
