If you have multiple photos of the same person or event, you can add different captions for each photo to help explain what’s happening in each one. To do this, open Instagram and click on the three lines in the top left corner of the screen. Then select “Edit Photos.” On the left side of the screen, you’ll see a list of photos that are currently being displayed. Click on one of these photos to select it as your default caption for that photo. You can also drag and drop a caption from a text editor into this field, or type up a new caption using the keyboard.
