I don't think the images being anchored is an issue. Since the same principle would apply to non-anchored images.
I'm just anchoring the header images so they remain in place with the text as I am still editing the text of the document. But here is a screenie. As you can see, the titles "Package Contents" and "Guidelines" are both graphical elements.
What I want, is that when I generate my Table of Contents, the software will output the text ""Package Contents ... 3" and "Guidelines ... 3" instead of "[image] ... 3"
Thus why I wonder if I can in essence, mark or tag the images, then have the mark or tag displayed in the TOC.
