Put an image here (PNG, JPG, BMP or TGA) and choose F1 > Settings >
Display > Borders > Image: it fills the window beside the game's 4:3
picture (the screens before the game with Widescreen on, the 4:3 movies,
or the whole game with Widescreen off on a wide window). It is scaled to
cover the window, cut evenly where it overflows, and the game is drawn
over its middle. With several images the first by name is used; without
one the sides show the game's picture blurred.

Images put here stay on this computer: the repository ignores them.
