See my attachment. Basically if you try to load wsj.com, there are many images that are css background-images which are actually overridden (not used) in the css, but are still downloaded by webkit. IE, Firefox, and Chrome do not do this. I've verified this behavior in both Safari, and Arora, which means it's not an issue with any specific port.

The attachment contains screen shots from the inspector and the actual HTML code which produces the problem.

hat_arrowBlue.gif is the file which should not have been downloaded. But if you look at the resource screen shot, you'll see the file was indeed downloaded. 

This is bad for bandwidth-limited environments.

Does this still happen for you with WebKit nightly builds from <http://nightly.webkit.org/>? I think that this has been fixed already.

Thanks. It does look like it's been fixed. Do you know which build it was fixed in and what's the original bug id?
