Logo-Folder: /Documents/Egosoft/X4/[Numbers]/logos/
Valid file formats are .BMP, .DDS, .GIF, .JPG, .PNG and .TGA.
Transparency in images should work as expected, but animations in GIFs will not play.
For the [Numbers] folder to be generated you will need at least one save-game, so the first step is to save your game at least once. After that, create the logos directory inside of the [Numbers] folder. The images you place inside the logos folder must be square and a power of two. A valid size would be 128x128, 256x256, 512x512, ... and so on.
After I placed the logo inside the folder, I had to restart the game and load the save-game. The logo will then show up for selection in the game. Press ENTER, click the tab Player Information and then scroll down to Custom Logos.
Hope that helped. If there are things I missed in my explanation please let me know.
