How do you make your display picture on what's app?

To change your display picture on WhatsApp, open the app and go to the "Settings" tab by tapping the three dots in the top right corner on Android or the bottom right corner on iOS. Tap on your profile name or picture, then select the camera icon or "Edit" option. You can choose to take a new photo, select one from your gallery, or remove your current picture. Once you've made your selection, confirm the change, and your new display picture will be updated.
