[arad26]

After the new kindle touch update when i send books to my kindle the covers are not showing anymore like they did before! I reconvert the books , send it again but it didn't work, even if i transfer them with the usb its not working! How can i fix this? Thank you!

Not sure, but I'm having the same issue.

I haven't looked at how/why it's done, but instead of being generated on the fly, they seem to be pulled & stored in the system folder. In the very few tests that I've done, I only got proper covers when downloading stuff from my archive on the device itself, or from a sync.

Putting a (still DRM'ed, metadata untouched) azw/azw3 from a 'Transfer via Computer' DL doesn't help (unless you happen to do a sync after, I haven't checked, wireless was off during my simple tests). (EDIT: I'm stupid, that's because I *sent* them via Calibre, and the asin got squished... cf. the multiple threads about it in the calibre/kdev forums)

FWIW, here's the filename syntax:

system/thumbnails/thumbnail_${ASIN}_${CDETYPE}_portrait.jpg

And the few that I checked are (badly) downscaled at around 232 or 262 px high (with a builtin-in fake drop shadow on the bottom right), and like before, don't seem to care much about aspect ratio, width varied much more than height.

(The 'portait' bit is slightly funny, because the Home screen doesn't handle screen orientation... Someone might want to check what happens with ixtab's orientation patch, though).

The framework does seem to sometimes try to build these from the file, because I do have broken/empty thumbnails of calibre generated newsfeed (with a .partial suffix)...
