It would be even better if an example logo image could be provided.

I am confused about creating images that fit the default size. If there were a standard sized sample image, it would be more helpful for beginners to create their own logo.

I didn't think of that, I could specify it in the description and maybe generate the image directly in the folder.
I will work on that but for now you can use the image you want, you just need to rename it splash.png and put it in /config/splashscreen

If the image is too big or small you can multiply it on the config file or with modmenu.
