This addon adds twitch type emotes to the ingame chat.
When installed, certain words in the different ingame chats will appear as emote images instead of text, as they would in a Twitch chat.
This addon does not access the Twitch API and thus emotes have to be added manually.
You can use the minimap button to browse what emotes there are. You can add and remove which streamers you want to see by going to: Interface > AddOns > Twitch Emotes > Uncheck the boxes you don't want to see on the minimap button.
There's also a toggle for 64x64 images (on select emotes) under your Inferface > Twitch Emote options.
