Thanks for the suggestion & links! Using the footnote feature is a smart idea. I also thought about that. But about 150 of my answers have both text and images. Many of the images have width=1250px. I know that some eReaders show footnotes in a small popup, so I don’t think they will show the full answer with image properly
