InDesign epub images are draggable after export. Why?
InDesign is great for making epub books. BUT I don't want to proceed with "marketing" until I have the answer to this "problem." Why are the images draggable in my exported epub books? (By "draggable" I don't mean "copy-able," that is a different topic). What I'm talking about is, unlike a PDF, where the image is securely fastened to the file, my epub images are easily lifted out by dragging). I have posed this question to Adobe and have tried all of their suggestions, unfortunately, after each attempt at one of their fixes, when I've sent my successfully completed (fixed layout or reflowable) epub book to someone outside of my "Adobe family," they report that they are (still) able to drag the images out of the book. I would love to know what I am doing wrong. Is there something specific that I need to do BEFORE export? OR, is this just the way it is with Adobe InDesign produced epub books? Thanks in advance for any assistance!
