Hello!, when i tried to import my own custom image into the mod config, the image was the same

The route of the backgroudn image was the same (background) was the same.

And they were both the same size / resolution (960x540), Any help?

Ohh i see, Alright, Thanks!

So the files on the .jar are basically useless?, Or do you have to change both?

It looks like you replaced the image in the jar, but you have to replace the image in the .minecraft/config/customsplashscreen directory

The files in the jar are just the example images that are copied to the config folder on initial load, you can ignore them.
