Note: These screenshots were captured in the Instagram application on iOS.
Step 1: On your Instagram home screen, tap the paper airplane icon in the top-right corner of the screen to go to your Direct inbox. Note: You can also swipe from right to left on the home screen to go to the Direct inbox.
Step 2: Tap the camera icon to the right of the thread you wish to send a disappearing photo or video within.
Step 3: Tap or tap and hold the capture button at the bottom of the screen to take a new photo or video, or tap the camera roll icon to import an existing photo or video from your device. Note: If you import a longer video, Instagram will break it into multiple clips that will be sent at the same time, and you won’t be able to change the video’s “disappearing” options. Also note that you can change to a different capture mode (like Superzoom or Boomerang) to take a new photo or video in that mode to send.
Step 4: Swipe right or left at the bottom of the screen to select “View Once,” “Allow Replay” or “Keep in Chat.” If you select “View Once,” your viewer(s) will only be able to view the photo or video a single time. If you select “Allow Replay,” they’ll be able to look at the photo or video two times in total. Finally, selecting “Keep in Chat” will prevent the image or video from disappearing.
