If a heavier weight than 120 KB is desired, the banner must be made with polite load (max. 1 MB). I.e. the extra weight must only be loaded on the browser event window.onload. window.onload must ONLY be used in iframe banners. The first load is often called the initial load, while polite load can also be called subsequent load.
The number of server calls from a banner must be limited to 15 calls on initial load and a maximum 10 additional calls for polite loads in order to not unnecessarily slow down the site performance. It is recommended to place as much content as possible directly in the banner code - and not in additional files that have to be downloaded first. In order to minimise the number of server calls, all external graphic should be sprite associated and optimised.
