Hitch
Thanks again for taking the time and effor to correct my error about images with external toc. I'll remember it when I work on my next external toc for an epub with images that I'd like to include in the toc.
Thanks to capidamonte, ATDrake, and Hitch, I finally found a variation that works with the internal TOC and also provides an appropriate external TOC without any caption space and with no validation errors.
Here's the internal toc:
<p class="noindent"><a href="../Text/Section0003.xhtml">Frontispiece.</a></p>
(This hasn't changed from my original post).
And here's the new code from Section0003.xhtml, that works with the internal hotref TOC and provides the no-caption external toc:
<div class="center">
<h3 title="Frontispiece." id="frontispiece.png"><img alt="frontispiece" class="size-1" src="../Images/frontispiece.png" /></h3>
</div>
Thanks for all the help!
