How to use graphics on Football Manager 2021?

As a player on Football Manager 2021, I'm having a hard time with the graphics. I am confused when using it. I think every player here will be informed about this. Can you tell me how to solve it?

Which graphics are you talking about? Custom files usually have readme files guiding the user on how to install them.

Logos, faces, trophies...go this one..
