How referrer information blocks portions of Web pages
When you open a Web page that includes graphics, the Web server for that page may use the referrer information to display the graphics. This happens when those graphics are stored on a different Web server than the one you are visiting. In this situation, the first Web server sends a request to the graphics Web server to obtain the graphics. The request includes the referrer information. The referrer information enables the graphics Web server to send the graphics to the correct location.
When you block the referrer information, the graphics Web server cannot send the graphics to the correct location, and you do not see the graphics that your current Web server would normally display.
