DOM when not an actual document
<p>Ok, lets say I go to <a href="http://www.google.com/intl/en_ALL/images/logo.gif" rel="nofollow">http://www.google.com/intl/en_ALL/images/logo.gif</a> , which is not really a document, but an image, iin my browser.  Does it still have a document object?  Can I use <code>javascript:</code> in my location bar?  Wha'ts the deal with this?  Thanks.</p>
