The main HTML document is (usually) not that big, and consists entirely of ASCII text. All of the images, drawings, colorful lines, etc. are .gif or .jpeg/.jpg files which are loaded separately and merged into the display by the browser. Even if you save the loaded page as a file and later reload it into your browser, the images won't be there and all you'll see is the icons provided by the browser itself, embedded in the text. Also, all good Web pages get updated regularly, so any effort to reload part of a page may be automatically doomed. There seems to be no good way to retrieve such dynamic files in pieces over time.
