How do you make a Config mod?

Hi!! In BeamNG, sometimes I would create my own configs, and then the thought hit me: Cant I make a config mod? I found a few issues, though.
1. How would I make pictures?
2, How would I make it into mod? My idea is to make it with no mods.
ill try working on it.

 

You can find out how to make a config here.

For pictures, you use the thumbnail generator in the UI apps.

 

Thanks
