The reason is given in the site discussion forum. We've recently upgraded our forum to a new version, and one of the only remaining items to rectify are the images. Our last version of the forum used to automatically resize the images, this one doesn't - yet. Give us a few weeks and it'll be fine again.
In the meantime if you want to see those images, just copy and paste the bit inbetween the img tags.
