I'm not sure adding HTTP headers will do the trick. If Wicket Ajax is
modifying the URL of the IMG SRC, but the URL is exactly the same as
before the AJAX request, will the browser even bother to reload it?

automagically? Either by having the JavaScript force a reload if image
resources or others are modified, or by adding anti-caching strings to
the automatically generated SRC urls?
