Well, Hitch, it does make Mobi-Sense, I guess. My solution now is to insert an <a> tag with the id in front of the main "illus" div. This works in the Previewer, and maybe it makes the devices happier as well.
<a id="cwa-01" /><div class="illus">
<img alt="" class="img095" id="cwa-01" src="../Images/cwa-01.jpg"/>
</div>
I never intended to work with mobi at all, and started out simply uploading AZW3. But I was questioned why I never uploaded mobi, and I took the plunge. I wonder how many more mobi-mangles I will come across ...
