Hi there, I am (as a GML beginner) building a 2D game with 40 1920x1080 static background pictures (mostly jpg, some png) and I like to reduce the volume burden these files will cause in the installation package. I am willing to lose some quality. But what option will serve my goal, using GMS2 and Photoshop CS6. I know that further compressing graphics does no good, but maybe there are real options, like: - reducing resolution of source files and scaling them up in GMS2 - using a different colour system - using a different file format - changing dots per inch - or what? What will help best? (For your information: so far I do not grasp the sprite_add with an included file; I must be doing things wrong, although I have read https://forum.yoyogames.com/index.php?threads/loading-sprites-from-included-files.15252/, https://docs.yoyogames.com/source/dadiospice/002_reference/game assets/sprites/sprite_add.html and https://docs2.yoyogames.com/source/_build/2_interface/1_editors/included_files.html).
