You could also try this way, putting the Chapter Name in a "title" and leaving the <h> tags empty.
I've used it sometimes when using an image for a chapter heading. I use Sigil, and it will generate the automatic TOC using the "title". Also useful to use this if you want the TOC to have different wording than the page display, you can put a different name in the <h> tags.
Code:
<body >
<h2 id="toc0" title="LA LIONNE"></h2>
<div style="text-align:center"><img alt="images1" class="frameGraphics" id="images1graphic" src="../Images/image003.jpg" style="width:100%" /></div>
</body>
