To change or add a contact's image, go to the contact details card. Tap on Edit, then tap on the image. You will have the option to take a photo, choose an existing photo, or create an avatar for your contact. If you create an avatar, you will be the only person who sees the avatar. After you add social networks to oneConnect, you can choose to select your contacts' social network images as the primary image for your contact.
If a contact you've imported into oneConnect has an image or avatar associated with it from Yahoo! Messenger or from your iPhone Contacts, that image or avatar will also be imported into oneConnect.
