Some sites contain images (an advertisement, for example) that resides on a different web server. When this image loads, it might attempt to load a cookie onto your hard drive. This test will attempt to load an image from another web site that I run (URateIt.com). This image will actually run a script which will attempt to write a cookie onto your system. As with the last test, the cookie will be set to expire when the test is completed, so no permanent cookies should remain on your hard drive.
