Pretty cool. One downside I see of the easy way of integration (as opposed to having to use a site-specific URL) is that the browser cache cannot be used (and as expected, the image comes back with a "no-cache" header), since the browser might end up using the same image for multiple sites using the feature. Is there any caching on the server to avoid having to generate the image every time?
