It isn't your fault, for some reason jackastor deleted the first post and changed the context for everyone who read the thread after post 5. If jackastor is still having troubles hopefully he will take PeterT's advice so we can help solve this problem. |

Jack has created another thread for the issue:
https://www.mobileread.com/forums/sho...d.php?t=141361 in which I've suggested a likely cause for the problem (that the cover isn't actually ending up in the book), but he's not yet replied to my post. |

That describes me. I read every post here, but couldn't see any discussion of a problem about kobo covers. I saw several posts about how to tell if the most recent update had fixed a problem with kobo covers and a post stating emphatically that this thread had nothing to do with updates - it had to do with kobo covers (which caused me to go back and read the posts again and decide that whatever this thread was about, it didn't describe a problem with kobo covers.)

Calibre can do one or two things: - Update the meta tag in the OPF for the cover image itself. - Insert an HTML cover page at the front of the ePub. The Kobo, like the Sony, ignores the meta tag, and instead uses a rendering of the "cover" page from the ePub. It seems like there are quite a few situations where Calibre won't replace the existing cover page, and rightfully so. That said, I've had Calibre refuse to replace a cover page it created and had some odd/blank covers due to the size of the cover image and not using SVG to scale the image. I have one which simply shows a blank cover which I can always poke at tonight since I was going to fix the ePub anyways. |

So what would be a workaround if one could? Any thing I have done seems to have random results. Sometimes it takes but most times it does not. Can never reproduce things twice in a row. regards Jack |

It is a combination of both. Calibre uses a meta tag to find the cover, as does iTunes and the nook. The Kobo and Sony both use ADE's cover renderer which renders the first page of the ePub. There is one way to create the cover page which will render right for ADE/Sony/Kobo, but Calibre will not mess with the cover page in an ePub if one is already present. It's pretty easy to make a cover page that won't render right. I've got a few I did by hand a couple years ago that are mostly white space, only show the upper left corner of the cover, and one or two with a blank cover.
The way to fix it is explode the ePub and fix the cover page manually. You can also make sure this is your problem by loading the ePub into ADE on your computer and seeing what it shows as the cover. |

I have a kobo wifi and had a similar problem not to long ago and it stemmed from a corrupted database on the KOBO ... I needed to restore the database for the Thumbnails of the books to show properly again. If you have alot of books loaded you may want to go the route of Kolenka has mentioned first ... In my case all the books listed after the corrupted record did not show the thumbnail properly. Another thing to try is forcing a hard reboot of the device ... for the WIFI version it is a matter of holding down the power button for 8 seconds this will cause the o/s to reload.

The answer appeared, as if by magic, one day when chaley was adding a Sony thumbnail enhancement I'd requested. It turned out that the Sony wanted its thumbnails to be a particular size. Once they were, all thumbnail problems disappeared... I wonder if there's a magic Kobo requirement no one has discovered yet? |
