Unfortunately, the image doesn't show. I think it is something to do with the number of posts you have. Same with the books. I think you posted links, but only the ISBN shows. To verify I found the right books, they are
http://www.amazon.com/Tony-Northrups...4094683&sr=8-1 and
http://www.amazon.com/Wonders-of-the...4094706&sr=8-1.
I don't own either, but I grabbed the previews. Both converted to epub with no obvious problems. And my Kobo Glo had no problem with them.
Flipping through the "Wonders of the Universe" on the Glo and Kindle PC, I can't see any real difference. Some of the images appear on a separate page on the Glo, but that is to do with the size of the images.
The DSLR book isn't quite as good. A couple of the sections have underlines through out. And there are a couple of spots where a new page is started after lists. The conversion seems to have split the book at these points. I don't know why.
Personally, I am quite impressed by how well the conversion worked and the Glo displayed the books.
I have the conversion options as pretty much the defaults. And I did a second conversion of the DSLR book with the options reset to defaults. There wasn't any real difference.
It might be something difference about the full books. The previews look fine, but maybe the full versions are causing the problem.
