If you are wondering how do I use the new GIF picker on Sakurajima Mastodon that we added today.
1. Click the image icon.
2. Select Upload GIF
3. Search for a GIF you want to add
4. Click on an image and it will automatically upload. Note that you might need to adjust search terms to see more results.
Note: This is only available on Mastodon Web. some Mastodon clients may have a GIF picker built in. Also, you have to be using the Glitch flavor of the Mastodon interface.
