You can create an Electronic Business Card without using an image, and you can remove an existing image from a card. You can also remove the image that is applied by default in the business card view of each of your Outlook Contacts.
In an open contact, double-click the Electronic Business Card to open the Edit Business Card dialog box.
Under Card Design, in the Layout list, click Text Only.
Click Save and Close.
