Add emojis to slack!
Add images you find on the internet to your slack team as emojis!
Just right click on an image, select "Add as an emoji to slack", give your emoji a name, and your done!
Easy as that.
Also makes adding emojis from slackmojis.com even easier.
Better support for large gifs and gifs with many frames will be added at some point in the future.
