This is more or less what Privoxy (new name for Junkbuster) does for me.

Cool, I might have to set it up again at home. Last time I ran Junkbuster, it broke all the images, and made the page look worse at times.

I do like the way Omniweb does it, it matches size and gets most banners. And if it's important to see, a right click on a menu choice will make it appear.
