Upgraded to Calibre 4 and all my book covers are gone.

FulciLives · 10-04-2019, 03:55 AM

The title says it all.

All my covers have this generic blue cover now.

Screenshot attached.

kovidgoyal · 10-04-2019, 04:33 AM

There have been no changes to cover handling in v4. Are the cover.jpg files still in the folders? Check by selecting a book and pressing O

FulciLives · 10-04-2019, 11:04 PM

I checked several of my books.

All of them have a file called "cover.jpg" which is in fact the book cover.

Still seeing nothing but those blue generic covers inside of Calibre as per my screenshot above.

Again this happened after I upgraded to 4.0

I didn't add nor delete any plug-in's etc. just did the update.

Maybe it's a conflict with one of the plug-in's I have (I do have a few installed just haven't changed any of them lately)?

kovidgoyal · 10-04-2019, 11:09 PM

Then run in debug mode (right click the preferences button) and post the output

FulciLives · 10-05-2019, 12:21 AM

Sure I can do that and thanks for your time.

I've posted the LOG to PasteBin:

Dont see anything suspicious in that, does it still happen if you run calibre from a command prompt as

calibre --ignore-plugins

And what happens if you manually set the cover for a book, does it show up subsequently?

FulciLives · 10-05-2019, 09:00 AM

The same thing happens if I load the program using the command prompt. In other words no change.

I did notice that my install path is this ---> C:\Program Files\Calibre2

Not sure if that has anything to do with it. Should it read 2 at the end? Note that I never did any change during or after installing so that's where it put it.

Another thing:

If I RIGHT CLICK on the BLUE GENERIC COVER and select "Open cover with..." then the cover opens up (I'm using IrfanView which is the program I use for opening images). Maybe this is because the "cover.jpg" images are in the folder with the ebook files?

But wait... it gets stranger.

When I go into the "Edit Metadata" and select "Download" for the cover it searches the net (Amazon, Kobo, Etc.) and then stops after a while finding nothing. I did this with 3 books and it did it with all of them, including one where I know I originally pulled the cover down from an online source. I've not seen this behavior before.

And maybe this is normal behavior? ... But when I try to manually select a JPG cover (using Change Cover: Browse in the Edit Metadata dialog) it says that it is not a valid format. Seems it wants a BMP or PNG or a few other formats (which are listed) but JPG isn't an option there.

Here is the LOG from when I try to Download A Cover in the Edit Metadata Dialog:

Did you hover the mouse over file type selector, viz:

If its not there, then it maybe something could be weird with your file associations - I lost a few a couple of weeks ago when 1903 turned up.

it looks like the jpeg image plugin in your install is corrupted. Do a clean re-install and you should be fine.

I remember doing that @BetterRed and my choices were very limited. Not like your choice options.

@kovidgoyal I will redownload the 4.0 install file and try a fresh install.

FulciLives · 10-05-2019, 04:11 PM

I did a fresh download of Calibre 4.0 and installed over the old one using the REPAIR function.

No change.

I then uninstalled Calibre 4.0 and rebooted the computer then did a fresh install.

Still no change.

By the way this is what I see when I try to manually set the cover:

You are trying to set a cover from within the Library??
I don't think that is allowed. First of all, if there was a cover.jpg(in that folder), you would have a cover shown in Calibre GUI.

FulciLives · 10-05-2019, 06:27 PM

There is a cover.jpg image in the folder.

That's really weird. There are various filters for file type - the one being used looks like it's called "Images" - I have no idea where or how they're defined. Add Books uses one called "Books".

Hopefully it will give Kovid a clue

FulciLives Connoisseur Posts: 51 Karma: 218936 Join Date: Apr 2019 Location: Pittsburgh, PA [USA] Device: Kindle Oasis 2 (2017 Model)	I checked several of my books. All of them have a file called "cover.jpg" which is in fact the book cover. Still seeing nothing but those blue generic covers inside of Calibre as per my screenshot above. Again this happened after I upgraded to 4.0 I didn't add nor delete any plug-in's etc. just did the update. Maybe it's a conflict with one of the plug-in's I have (I do have a few installed just haven't changed any of them lately)?
