Justin can't control the ads shown, Google does. We all know that server's not as good as EMC though, so it's not really much of a problem.
You will find that google displays ad's In accordance with your recent searches and visited webpages.
Not sure what the image was but I read somewhere, possibly in one of the other "Omg Ads!" threads that if it's advertising another server you can send the screenshot to IcecreamCow in a PM and it can be removed. I did it and he invited JustinGuy who removed it.
