I agreed with him implicitly. No, in the case where we filter ads we do so because they cause specific pages to be delayed in loading. Altavista for example would not have their ads filtered because they load quickly and are fairly well integrated with the page. By filter I mean 'do not load images that match a specific set of criteria'. Since you're somewhat slow I'll explain how HTML/HTTP work with respect to loading these images. We've got an HTML doccument: http://www.foo.com/foo.html Foo

Foo

This is the content of foo. This is only the content.

Two additional requests are needed in order to completly load all components of this page. The page merely asks us to load them. Our browser is under no obligaton to honor these requests (we can even turn of image loading completly if we desire.) By use of IJB and others, we give ourselves the ability to do a number of useful things (not load images, de-interlace interlaced gifs, etc.) This is the nature of the web. Complaining about it does no good. Accept it, move on. Just think of what web caching proxies do to banner stats on static pages. (Which is why most banners are on pages are dynamic and provide hints for caching proxies not to cache them.) /* Matthew N.
