Not all displayed covers have a thumbnail. The cover for "A Christmas Carol" was generated by the Kindle itself when the book was placed in documents over USB storage. (I guess books didn't come with jpeg thumbnails back in 1843.) Last edited by knc1; 06-01-2013 at 10:42 AM. |

 What I know about the PW covers, I mostly learnt from the forum here, with the origin probably this thread on the Calibre forum. https://www.mobileread.com/forums/sho...d.php?t=193805 https://www.mobileread.com/forums/sho...d.php?t=192561 The thumbnails folder is system/thumbnails The thumbnail filename rule I dont' know for sure. Seems to use the UUID or ASIN or something. You could check the Calibre source code (or ask over there) The thumbnails must be max 330 px high (or so - I don't know the exact limit). Probeably there's a width limit too. If I remember correctly, (I read that stuff a month ago), the Kindle Touch uses a similar approach, but needs even smaller thumbnails. OTOH, the Android apps for instance, happily retrieve the cover from within the .mobi file. HTH

Thanks knc1, fred_be9300. I have updated my Klingon guide which can be grabbed from a spoiler on the OP to v0.4. The contents has not changed other than trying to enable proper cover view (on the Touch and PW) by
1- Creating a 180x240 thumbnail from the 600x800 cover 2- Adding the thumbnail metadata in the .opf 3- Kindlegenning 4- Using MobiMetaEditor to add a fake¹ ASIN=B000KEB6WW and CDEtype=EBOK in additional EXTH (113, 504, 501) records. I didn't test, not having these devices. Let's call it tentative until someone reports results. [EDIT] Ah well, didn't work : lex1000 tested it ¹ This ia a real product ASIN, which I selected to insert more easily the metadata, it is just not one for a book.

@PoP: IIRC (it's been a while), provided the ASIN is valid (ie. not a Calibre UUID), and the metadata pointer to the thumbnail is correct (both Calibre & Kindlegen handle that properly, provided you have a decent cover, AFAIR), the Kindle should build & cache a thumbnail from the book itself.
(I think fred_be9300 managed to dig up most of my better answer on this very subject from the Calibre forum  ).Where it can get tricky is that there a weird bit of caching involved, and if you 'trick' the Kindle by *replacing* the file from outside of the OS (ie. over USB/SSH), all hell breaks lose and the catalog gives up on the thumbnail, even (or especially, can't remember) if you supplied a thumbnail jpg yourself. So: delete the file *from the Kindle itself*, then upload a new version. (AFAICT, what you did seems correct, I'll take a look at it with KindleUnpack, though). I mostly work with KF8 files, so there might be an extra weird step for KF7 files... EDIT: Ah, yes, now I remember. There is indeed a bit of trickery involved depending on the format. KF8: It doesn't build the thumbnail from the book, it downloads it from Amazon's servers (thus the requirement on a valid ASIN). If, like Calibre, we sideload the thumbnail ourself, we don't care about the valid ASIN requirement, it works fine with a Calibre UUID. KF7: It does build it from the book, and yours is properly setup, metadata-wise. So, err, I guess with a combo file, since those devices are KF8 aware, it defaults to the annoying KF8 download thing, which is why we sideload the thumb ourself in Calibre. My warning about the weird caching of the cataloger still applies, though, since I definitely remember it biting me on the ass during my initial Calibre tests .As for the PDOC banner/cdeType, I don't *think* it has any other impact on all this, although, again, I do most of my tests with EBOK cdeType, not PDOCs .EDIT²: If this post doesn't make any kind of sense, it's on me. I've been staring at my backlog of posts for a few hours now (wee! 3 months and a half left! xD), and I'm calling it a night (well, an early day, I guess, since it's now nearly 6AM, *sigh*). EDIT^3: Wait, actually, it does have an effect. I think KF8 PDOCs also fall back to the built-in thumbnail, but you have to live with the personal doc banner.

Thanks for your explanation. It *does* make absolute sense despite your backlog
True : I wanted to use the EBOK cde type to avoid the personal doc banner. Yep, I think sidereplacing the book (instead of OS deleting + re-sideloading) is a likely culprit for cache corruption. My OCD won't let me sleep well until a capable and willing user retests the procedure... or I buy a PW myself

Metadata updated in my guides.
After learning something more from dimasic and NiLuJe (thanks guys).
I have updated my 3 guides (metadata only, no new content) to Klingon v0.5, Vulcan v0.3, and Ferrengi v0.2. I am hoping that upon sideloading the .azw or .azw3 split components, thumbnail cover view will work consistently and the personal document banner will not show up. I have split the combo .mobi generated by Kindlegen and I have included in the archives the KF8-only .azw3, and KF7-only .azw components after modifying their metadata per post#64 Grab them from spoilers of the OP Last edited by PoP; 09-24-2013 at 04:10 PM. |

Tommy, you are off topic... Really‽
Today I changed my « My User Details »¹ to ⠋⠑⠑⠇ ⊻ ⠟⠥⠺⠎⠞⠺⠕⠺⠁⠞⠾ ≡ 0 and felt that I owed an explanation.
When I edit this field, it needs to have the following seven⁴ attributes. 1) It has to be terse (the explanation *can* and perhaps as this one, *should* go to great lenghts). Why settle for 140 characters à la twitter when you can constrain yourself further to a ≤25 characters of the User Details field. 2) It must be enigmatic and puzzling (but must never be totally cryptic or hermetic). That is the fun part : finding what it means. And the more layers the better. In my example, the ⊻ and ≡ mathematical symbols² are at the first layer of the puzzle, indicating that XORing the terms together is identical to zero. But at the second layer the Unicode Braille Patterns are not even the same, so how can XORing them solve to zero? This leads to the third layer where one learns that Braille Patterns are symbols *without* connection to an alphabetic letter or number. 3) It must be meaningful. There must be a message or an idea to convey. It must be sensical and if there is a context it must be related to it. In this case I posted this explanation in the thread about my Nadsat Translation Dictionary to indicate that the fourth layer of the puzzle involves a translation. Since the Braille Patterns are not tied to a single language they act like a one way function. Finding the source language which lead to the Braille code is not easily reversible but here is a tool to help you out . Nadsat should already have hinted you that the first term is english-Braille for feel and the second one russian-Braille⁵ for чувствовать . This is the fifth layer of the puzzle. If the Braille was embossed (who knows, maybe are you reading on a haptic screen) you could feel *feel*. At this point you could cheat and ask for a Google Translation, but since this is about math, you already know that at this sixth layer the terms must have identical meaning (if not identical representation) since XORing them is ≡ to 0. And finally, there is a seven layer⁴ᵇ (the one where all of it started) and contrary the title it is not off topic other than this other thread : about Tommy. 4) It must be specialized and consistent in style. À la Randall Munroe , if you ever followed the series of updates, my main subjects of interest are Language, Math and History. 5) It has to be somewhat appealing. Using fancy Unicode helps a lot here. Well, if you read this far, it must have attracted enough of your attention! 6) It benefits from being Hyperlinked with explicit web references and more subtly by cameo appearances. In my errand searches, I inevitably discover something totally different. For example the title of this post contains a cameo of my previous User Details edition U+203D≡ᴳᴺᴬᴮᴼᴿᴿᴱᵀᴺᴵ≡8⇂Ǝᄅ+∩ . And the links I have sprinkled throughout will hopefully send you in different paths. 7) It is an Open art where you must not count your time³. I primarily craft this for *me* and I spend much more time than I will admit to. I sincerely hope it will catch your interest, but I don't expect nothing in return. I share it freely, kindly and respectfully. And if you use it I will certainly follow you. NOTES: ¹ I know. Some users set their forum preferences so they will never see any of it. See all they miss! ² A shame that I couldn't find a more elegant APL math operator for this. ³ It is a hobby after all. ⁴ Seven is a good number and I had to stop somewhere. ⁴ᵇ See ⁴ ⁵ BTW I don't speak or read Russian |

Just a minor fix. The dictionary entries can now be extracted with KindleUnpack. Thanks KevinH.

thumbnails
Nice find:
In posts #14 and #15 of this thread is a program to create thumbnails from the cover images and to force sideloading them to the /system/thumbnails directory. Thanks for sharing quiris! I am hopeful this will finally solve the cover-not-showing issues. |

v0.8+
Changed the metadata of the dictionary and the three guides (named *_new.* in the zips) and added the corresponding thumbnails which can be sideloaded to /system/thumbnails
The metadata is per post #64 with fake but new and unique ASINs. The thumbnails were generated by quiris program per post#74. YMMV: I am doing this blind/untested on a K3, hope it works for you Grab them from the OP. |
