In case you hadn't heard, Facebook recently announced that it will officially support the use of gifs within user News Feeds. Previously, gifs could not be played natively in feeds and could only lead people onto external sites.
Lots of people think that Facebook has had the capability to support gifs for quite some time, but that they've only chosen now to unveil the perk.
The feature doesn't work for fan pages (boo!) but personal accounts will now be able to host the moving pictures from tumblr, giphy, and other sites.
Step 1: Procure the gif URL (it will have the .gif extension)
Step 2: Paste the URL into the status update box
Step 3: Voila!
