Hi --
I had the same question a few weeks ago and couldn't find a more recent version of KindleGen. I downloaded the one on Amazon and it works fine with my Win 8.1.
BTW, I use Scrivener for formatting, it's available for a free full-featured trial. The image import feature works great. I noticed a message on the KDP desktop about kids book, manga and so on. If someone with experience with picture books doesn't come along soon, that link might be a good place to start. After you log in, it's on the page where you upload your book to KDP.
You can download KindleGen and then tell Scrivener where it is, or use an epub file to upload to KDP.
