Hmmm... No, it's not only one image, it's every image that's referenced multiple times (and it's included as many times as referenced). Maybe you are thinking of the cover image being included twice if no thumbnail is given, that's probably the same (or very similar) issue, but I agree it would be minor if it only affected a single image. However, in this case it would affect all 135 illustrations (thats 8MB even with the 64kB limit), every time I reference the illustrations, the filesize would increase at least 8MB...
