Ah, is that hand-carved HTML? I thought it was CSS. The trouble with style attributes in HTML is that different browsers are liable to treat them differently. I would recommend adding hspace=10 (or some other number) to the <img> attributes, to put some space in there so it doesn't collide with your bullet points ... but on somebody else's browser it might be too much.

I don't know how to clear the float at the end of the post, so that it doesn't overlap the comments, without using CSS, but a <br clear=both> might do it, at the expense of extra white-space.
