Yes, that is what it's supposed to look like. I just checked after seeing your message and it works for me now too. Therefore, it is intermittant. When I noticed it the first time, I reloaded the page several times. Then exited IE and reloaded. the images still did not appear.
They DID load after your first repsonse. But lapsed back to a no-show later.
I'll check the site later and report in if it happens again.
Could it be an overlaoded server?
