Hi,

Quote:
Our disparity lies in the fact that Aaron says he is no longer getting images in the mobi8 folder when extracted, while I still am. We both still find images in the mobi7 folder.
Then he should post a sample ebook that illustrates this problem and send me a link to it (use PM if you want privacy) so that I can recreate the issue and get it fixed.

The reason for the query, aside from the missing images in the mobi8 folder, is because we're trying to ascertain how Amazon is sourcing the higher resolution images for the HD devices, now that a 5 Mb per image file size is allowed. Do these come from the kindlegensrc.zip archive, or the .azw3 file?
Neither. There is now a third part of the kindlegen generated file added after yet again another "separator" that is called an HD CONTAINER that stores all of the HD images, one per sector of the palm file.

I am not sure that anyone has bothered to decode or dump those as they are only produced by the latest versions of kindlegen. There is a program called DumpMobiHeader_v14.py someplace I wrote that can show you where they are being stored in the kindlegen generated mobi file. I will loook and see if I have a later version of it and post it for you to help you find these HD container files.

Mainly I was trying to account for what is in the final converted file, and the missing images are an unknown variable. So my question is whether anyone else is seeing an empty images folder in the mobi8 section of the unpack? Or is this an anomaly?
There is no such thing as an anomaly, just a bug. If you can please post a link to a sample ebook that illustrates this issue, I will try to get it fixed.

For the record, here is what Aaron is seeing (and this is in an unpacked version of a preview file downloaded from KDP):

Zipped submission archive (with uncompressed images) [kindlegensrc.zip]
Mobi7 source folder (with compressed images)
Mobi7 ebook (with compressed images)
Mobi8 source folder (no images!) ***
AZW3 ebook (uncompressed images)
Kindlegen log
What do you mean "compressed" images versus uncompressed images? This could be the source of the problem but I need a sample ebook that illustrates the issue if you want it fixed.

Take care,

KevinH
