That was an old post. We used img-tags back then. img-tags will now turn most images into links. To make it display in posts the "old way", you should now use ats-tags instead, if you host the image. ats-tags are not to be used for hotlinked pictures. Only for photobucket, imageshack, uploadit, or ats, etc. Not hotlinked from blogs or articles. If you host the image, you also don't risk it suddenly turning into another image, or removed by somebody else.
