What's making this odd is that the comments and the image that the code I noted before was all in the same table and the image displays properly. Looking at the source code directly off the page, there's a </Center> tag right after the image. I'm not sure if you added that or not, but that wouldn't help. Based upon the code I noted and my own page's code, you need to make sure that the comment script and the comment form script are in their own <tr> tags if you want one above the other. Also make sure the <td> tags force a width and you may need a colspan=2 to properly center it.
Beyond that, there's not much more I can do without being able to tinker with it myself.
