Sandbox

When I first enter Joomla.com all the images are missing (the standard box with the red x).  If I go into any other tab (the Forum, for example) and return to the homepage the images are there.  This has been going on for a couple months now.  Any reason why?

simply use http://www.joomla.org. That's the official domain, the other one isn't ours to my knowledge, but only a forward.
