Allow the developer to easily add images and gifs to comments
This extension enriches Github comment box. Typing "!" inside a comment box will open up a box where you'll be able to search for the right image/meme/gif you want to place inside the comment.
In addition, each media has a name and if you already know the name of the image/meme/gif you want to use, you can simply type $image/mem/gif_name$ and it will be replaced by the desired media.
Now go and make that code review process much more fun :)
