Any way to put an image into the chat?

I want to have my own custom rank icons for VIPs but can't manage to add an image before the player's name, is there any way I can do this?

At least for Rust, from what I know it isn't possible to add images in chat, other than the player icons / profile pictures.

And Better Chat does not support changing the profile pictures, as it doesn't really fit with its purpose.
