If I understand you correctly, this is really a web server issue and is
handled by the 'Alias' function in Apache (other servers may call it
something else). This function allows you to set a path prefix - say,
/images - and have all references to an image resolve to the same place.

So in your code you would have <img src="/images/foo.gif"> and it would
resolve to /my_web/images/foo.gif regardless of where it was referenced
in your web document tree.

Aliases may also be used for css, javascript or any other commonly
shared code elements.

Hope this helps.
