Creating a background manually
GoldSrc background images are split into TGA tiles.
Creating the tiles
The tile files are indexed by 
.resource/BackgroundLayout.txt and .resource/BackgroundLoadingLayout.txt. The files should usually have the same content, although there are some cases you could use different backgrounds. See 
Condition Zero Deleted Scenes for example vanilla usage.
Note:Since the 
Half-Life 25th Aniversary Update, the engine uses the files resource/HD_BackgroundLayout.txt and resource/HD_BackgroundLoadingLayout.txt if liblist.gam has hd_background "1".Specifications
