No, there's 100s of GB still available! I had checked the location of the images and they are all there.
Not sure if maybe apache has gone a bit strange, but I'm running a few other web pages off the same box and they all work fine. Ebox was running fine, until I logged in yesterday. In fact it still works perfectly, just minus all the images. Clicking on 'view image' in firefox gives me a 'not found'.
