I am not sure where this bug should be submitted and have been looking for a week or so.
When I go to http://Joomla.org/ and am not logged in, none of the images show up. When I am logged in the images show up. It appears that the images are tied to registered/unregistered users??? I have attached a screenshot.
I have been able to recreate this issue twice. The problem (pictures showed up) went away when I logged into the forums section of Joomla. The first time I was only logged in for 1 day (or some time period other than permanant). After this time period expired for my loggin, the problem reoccured (the images went away).
OK - I just tried a test again on another computer where I am not logged into the forums section. The images do show up for Joomla.org but do not show up for Joomla.com!!
When I just went to Joomla.com first the images didn't show up, I then went to Joomla.org and the images showed up. When I hit the back button and returned to Joomla.com, the images showed up.
joomla.org is our primary domain name, the others are just parked/aliased. We've had to enable hotlink protection to joomla.org and that is why you don't see images on the .com
