caching

Is it possible to control with javascript whether a browser goes to the server for an image or to the browser cache? Can I force the browser to make a server call when it would otherwise use a cached image? I know I can simply append a query string to my image url, but, if I understand correctly, that works because the browser sees that as a new image. I want the old image to be replaced in the cache.
