The image will be stretched to fill the screen without maintaining aspect ratio – so bear this in mind when adding text, logos or other fine detail to the images!
Menu Backgrounds
The game will choose a random menu background image from files named "backdropX.png" (where X is a number, starting at 0) in the "bdrops" folder.
You can overwrite an existing image by using the same filename (eg. "backdrop4.png"). You can add new images by using numbers greater than 6 (as of Warzone 3.1 Beta 10 - may be more default images added in future).
End Credits Screen
The end credits image is shown on the Exit Screen. The image must be called "credits.png" and be located in the "bdrops" folder.
Unlike menu backdrops, there can be only one credits.png screen.
Your credits image should mention Pumpkin Studios and EIDOS Interactive, the original developers/publishers of Warzone before it was released as open source.
