Or simply change the URL. If you call images by their absolute URL
whenever possible you will not only make it easier to count them in your
logfiles, but you will also help the browser cache properly.

When the browser (and web proxies) see relative urls such as above, they
have to retreive the new relative image, since they don't realize they
already have the image. if you use the method I propose (and use, btw),
they see an absolute path, and having already retreived that image, use
the cache.

So, you could put all your images in /img and then call <img
src="/img/myImg.jpg">, and save bandwidth as well as zope processing. :)
