Thanks. I tried the whitespace thing, but no difference. One requirement for the assignment is that the code must validate as XHTML 1.0 Strict. If it doesn't, I get zero. So I think I've been quite anal about code correctness. Still, there's always room for things to go wrong.
Sample code:
HTML Code:
<div id="header">
<div id="logo"><img src="Webdoken logo.png" alt="Webdoken logo" width="243" height="73" /></div>
<h1>Webdoken™</h1>

</div>
The divs are for applying CSS. The alt text displays the same way with or without it, except that with the CSS the alt text adopts the font of the "header" div.
Most of my Firefox testing has been with 3.6.13, although I'm quite sure I've also tested it with 3.6.15.
