As you may recall, I recently switched to GitBook.io as my primary publishing platform. Alas, my GitBook.io experiment didn't last long. Everything worked smoothly until I encountered a rather serious issue: for some reason, EPUB, MOBI, and PDF files generated by the service didn't include any images. I duly submitted a bug report and tried to contact the developers via Twitter, but I got no response.
This is not the end of the world, of course, but it's a good reason to find a better and more reliable alternative.
