This server will inspect the User-Agent header of the HTTP request and serve a fake image for the Discord Bot.
Opening the image in the browser reveals the real contents.
Requires 2 files in the working directory: praying-jesus.jpg and praying-jesus.webm.
The .jpg gets displayed for the Discord Bot and the .webm for everyone else.
Visit http://127.0.0.1:54299/praying-jesus.jpg when running the server. To see the effect change your User-Agent string to Mozilla/5.0 (compatible; Discordbot/2.0; +https://discordapp.com) and reload the page.
