Make Character.AI avatars load in their full resolution (400px) and quality (100%), and let them be animated when they should be. I also try to manually find sources of characters' images that are recommended to me by CAI, WARNING: There is some (mostly furry) NSFW content. Great moderation going there, CAI.

This script absolutely works, and I highly recommend it. 👌👍
