If it works, then it is indeed the file size that is the problem on the PW-3.

Well that didn't work... got the file down to just over 1.6MB and it still doesn't like it. God only knows then. I'll just do without this one

@Yolina: 1.6MB sounds like *a lot* for a true PNG8, even undithered and at the relatively high PW3 resolution.

If you can, try to process them through ImageMagick like the cover mode does (I linked to my latest post a few pages back, I think).

I've got another couple of large ones (1.63MB and 1.39MB) which work fine but yes, it's creeping up with every new higher res device.

Thanks, I'll try that tomorrow. Been using Photoshop.

Right, I started again from scratch with the image in PS, including re-converting to grayscale, etc and this time the PW3 is happy with it, file size is also much smaller. No idea why the PW2 didn't have a problem with it but the PW3 did.

Thanks all, and sorry about all the hassle

The answer was given five months ago (a ways back in this thread, even with a setting of 40 posts per page):

Your mysterious image problem is now immortalized in the FGA list.

Ah In my defence, the last time I played with my screensaver images was well over 2 years ago

Nothing personal intended.
It just took me awhile to find those links.

NiLuJe's "a few pages back" must have suffered in the translation from French.

Now, now... I am French too you (probably don't) know

I have KV 5.6.5 with BD jailbreak, with linkss-0.24.N-r12851 (from snapshots). I have problems extracting covers from *some* kfx books, those with some non-ascii char in filename. Ej: Fool’s Errand (The Tawny Man Trilogy, Book 1)_B005JE1KD8.{kfx,sdr} This is an english language book but with a non-ascii tilde in filename.

Running kfxmetada.py manually from command-line, it says:

  File "./kfxmeta.py", line 100, in main
    print('Decoding "%s"' % args.infile)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 28: ordinal not in range(128)

Inserting at line 100:

args.infile = args.infile.decode("utf-8")

fix this problem, but I suppose this isn't the proper encondig-independent solution.

NiLuJe, thanks for your outstandig work!

@nemiere: Yaaaay... Thanks for the detailed report, I'll look into it .

@nemiere: Should be fixed (I hope ;p).

[nemiere]

@NiLuJe last snapshot is not working in my KV...
Trying kfxmeta.py directly over the metadata file, the problem still shows:

$./kfxmeta.py "/tmp/docs/Fool’s Errand (The Tawny Man Trilogy, Book 1)_B005JE1KD8.sdr/assets/metadata.kfx" /tmp/cache/
KFX Meta v1.1.N
Traceback (most recent call last):
  File "./kfxmeta.py", line 415, in <module>
    main()
  File "./kfxmeta.py", line 138, in main
    print('Decoding "%s"' % infile)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 14: ordinal not in range(128)

[NiLuJe]

@nemiere: Oops, forgot the most important part :x. Should really be fixed now .

[nemiere]

@NiLuJe: although kfxmeta.py perfectly works running from command line, linkss extension still doesn't work on itself. I'm using last snapshot (kindle-linkss-0.24.N-r12903).
Kindle logs only show:
