An authorized user is allowed to personalize an existing third-party webpage. A request is received from the authorized user to insert a user-selected image into the third-party webpage. It is then determined if the user-selected image is appropriate for use on the third-party webpage, where this determination is based on one or more image appropriateness criteria. Whenever the user-selected image is determined to be appropriate for use on the third-party webpage, the third-party webpage is personalized by inserting the user-selected image into the third-party webpage according to the authorized user's image insertion request.
