Rotating Ads are a number of images that are displayed consecutively at the same spot. The images are only downloaded once, yet the ads will continue to run continuously while the viewer remains at the site. These ads attract more attention than the standard banner yet one must be careful not to run too many images. The constant change and repetitiveness can become an annoyance to the viewer. In addition, since long exposure is needed form the banner chose sites where the viewer is likely to stay on the same frame for longer periods of time.
