I don't have the icons up at my house because I've set the Proxomitron to block off site images. If you haven't specifically done that, maybe some sort of server block is in effect offline?
When I had icons visible, sometimes they loaded slowly when the Cache was flushed. So maybe your image Cache is full and you've got some setting preventing it from loading new images.
Or something.
