Hi,
Well, i sometimes capture pages with articles, sometimes loaded with images that don't really have anything to do with it, that's where it might be useful.
But there's a better way: Almost all pages now have a print-mode with few or no images. Having Netnotes capture a link when i right-click on it (instead of the currently displayed page) would solve my "problem", plus it should be easier to implement and seems to be a feature useful for other people besides just myself. :)
