Twitter on Android and iOS has received a new feature in a recent update that allows the integration of text, photos, videos and GIF animations in a single tweet. Reverse engineer Alessandro Paluzzi discovered the feature back in April, and then Twitter officials promised in July that they were working on it.
At this stage, only one type of media can be shared in a tweet. All you need to do is click on the photo icon in the tweet editor and add the media of your choice. The content you add will be displayed side-by-side or in a grid-like format, depending on the number of images, videos or GIFs you add. You can see how this might look in these tweets shared by Twitter.
