ExtractCoverThumbs uses a newer and more functional version of the kfxmeta.py script. It is able to locate the cover image within a KFX file containing multiple images. It is not 100% correct but far better than the older version that the SS hack uses.

The version of kfxmeta used in the screensaver hack was changed quite a lot from what I originally produced. I assume that was done for compatibility with the Kindle environment. Updating it to use the logic from ExtractCoverThumbs will take a lot more than a simple cut and paste. There were a LOT of changes added in the version used by ExtractCoverThumbs in order to make extraction of the correct image happen.

Could you please try to fix that cover extraction problem? |
I am not going to undertake that effort since I am not familiar with the Python environment used, do not have any jailbroken devices on which to test the results, and my Kindle already displays cover images for KFX files on the sleep screen.
