If you want the full rundown, head over to the DrunkenBlog post using something like Firefox, Camino or Opera - just not Safari, OmniWeb or any other WebKit-based browsers. If you visit the post in Safari, it will crash; this has been tested in the latest 10.4.5 update on both PPC and Intel versions. Also, whatever you do, do not download the image to your desktop, especially if (like me) you have the Finder option to "show icon preview" turned on. It'll crash Preview and send Finder into a constant crashing/restart cycle.
Like I said, you can get the full, in-depth rundown (and I mean in-depth) on this issue and its specifics at the DrunkenBlog.
