Actually, that's a good little quick test.

Conficker (and certain other worms) tamper with your system's ability to reach certain web sites, specifically, any AntiVirus site that could possibly help you detect and remove it. So, if you have an infection like that, you would not see the images on that page that are sourced on the AV sites.

When diagnosing possible client infectons over the phone, we usually ask them to go to symantec.com or mcafee.com, just to see if they can view the web site. If they can't...but can see most other sites...it means they've caught something.
