YSlow team released new version – 2.1.0 and among other things, they added a new rule Nikolas Zakas came up with for checking if there are any images/scripts/other external files that have empty URL.
This means that new release of ShowSlow – 0.11 now supports this new rule! We’ll be upgrading testing servers on ShowSlow.com soon, meanwhile you can send data in from your own YSlows.
Just follow upgrade instructions if you already have an instance running: http://www.showslow.org/Upgrading_existing_instance
Or you can download the package from Google Code:

and install it:

Let me know if you’ll have troubles upgrading and don’t forget to vote for bugs in the issue tracker:
