I recently came across this image which seems like a normal GIF:
Even imgur stores it as a GIF when I uploaded it here.
But when I saw the link, it was a JPEG image, unlike a GIF than what I had expected!
Here's the link: https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash3/559307_325955130827518_630404691_n.jpg
