One of the fun capabilities of IO is a reproduction of Microsoft Comic Chat from the late 90's. We welcome anyone to submit a pull request with a custom avatar for their Twitch account.
The requirements for an avatar are pretty specific. You need two images: head-{twitchHandle}.png & body-{twitchHandle}.png. Both should be transparent PNGs.
We've created a place to test your images at codesandbox. You can reach it at https://codesandbox.io/s/quizzical-mendeleev-0gwnq. Follow the instructions there to get your body & head images just right and then submit a pull request adding them to the /assets/images/characters/{your twitch handle} path.
