Instagram is a social media platform that allows users to post pictures and videos of their lives. To access your Instagram camera roll, you must first create an account and then sign in. Once you have signed in, you can access your camera roll by clicking on the three lines in the top left corner of your screen. The first line will show you all of the pictures and videos that have been uploaded to your account since you last logged in. The second line will show you all of the pictures and videos that are currently in your camera roll. The third line will show you all of the pictures and videos that have been added to your account since you last logged out.
