Once we have located the person whose photo we would like to add, we will tap their name one time
This will open up the contacts profile for us. From this page, we need to focus on the dark gray bar located at the top of the screen. On the right-hand side, there will be a star icon in gray. There will also be a white icon of a pencil.
This is going to open up a new page for us, where we can edit various things about our contact
This screen will be labeled "Edit contact", in the top, left-hand corner. We can see just to the left of the person's name, there will be an icon for a profile photo. In the bottom right-hand corner of this icon, since we do not have profile photo set, there will be a small, white circle, with a plus sign inside of it. Pressing this will allow us to add a photo.
This will bring us to the contacts page once again, where we can see our newly added profile picture
To exit our contact list, we will press the Home button one time. This button is located in the center, directly under the phone's screen. This will take us back to the Home, closing the Contacts application for us.
