F5 does not recognice Exif-Thumbnail change.

[brotondi]

[x] Use embedded Exif-Thumbnail
Update Exif-Thumbnail with 3rd-Party-Tool (or rotate with 2nd XNView)
Press F5: The Thumbs will flicker but not be changed
(This is the Bug)

Now Change "View/Thumbnail Size" -> All Thumbnails will be updated and now be correct.
(This is the control)

... Only a little bug but if you add an Exif-Updater it will get important.

It's not really a bug because the embedded thumbnail is not changed....

??? don't know what happened, now I cannot reproduce it too...

it seemed, that XnView was not able to re-read the Exif-Thumbnail, even after a change... but now everything is o.k.

...

when it happens againg I must have a sharper look on what happened really...

Have a nice day!

I set up a new PC and installed this new version of xnview. I previously used the last version of xnview and this new version is not recognizing the flipped thumbnails but the full sized images are oriented correctly. Weird.

The thumbnail size trick works but this is annoying.

Hi

You must know:
-In Exif there's an orientation flag AND the thumbnail
-But there is no relation between them.

If a tool turns the thumbnail but does not set back the Flag (I think some older XnView-Versions) this will happen.

(I Think this is what you saw)
