GIFs are everywhere on the Internet and now you'll see more of them on Twitter. The company just introduced a new GIF search engine for you to find and add the moving images to your tweets and direct messages.
Twitter added support for GIFs way back in 2014, but you had to find them on a separate site and upload them yourself.
Now, you can just click the GIF button when you compose a tweet or message and browse popular categories or search with a few keywords to find a GIF. You'll only be able to post one GIF at a time and you can't share a regular, not-moving photo and a GIF in the same tweet.
