Yeah, I loaded this page in Firefox 1.0 (final release) today, and some of the images were missing. The Penny Arcade logo in the corner, the new post indicators on the side, new post buttons, new thread buttons, etcetera. I've checked this on two different computers from two locations and I get the same results. It didn't do this yesterday.
It works fine in IE, too.
Crossposted from flipside because I get the impression META is more about moderation and banning and such specifically while Monkey Den would be the place for stuff that affects the site and database itself, especially considering it's happening on both sides. I hate crossposting but I don't think I'm the only one with this problem.
