GIF avatars, the company claimed, were never supported, even though users had countless tutorials for sneaking past the restriction. In September, Twitter closed those loopholes.
Thanks to a hidden Twitter API loophole found by Indonesian programmer Citra Kasuma, GIF avatars can be added back. Here are the six easy steps:
1) Visit http://twit.kakiteng.com/ and click the "Sign in with Twitter" button.
2) Plug in your Twitter credentials.
3) Select "Edit Profile."
4) Select your GIF animation.
For best results, GIFs should be sized at 128px, 192px, or 384px; less than 250kb; and not have a transparent background.
5) Once your avatar is uploaded, go to your Twitter settings → Apps and revoke access to the "Kakiteng c Kusuma" app.
You may also want to change your password. This is to prevent your account from being compromised in the future.
6) Sit back and enjoy the GIF.
Most GIFs will animate in the Twitter's Web timeline. Depending on the browser you're using, the size of the GIF, and whether the app is working properly, your success may vary. It is a loophole, after all.
