XnView Software

Yes, of course, but it would be very helpful if there was at least a confirmation prompt here.

Something like this:
You have made changes to the photo.
Should the modified version be renamed?

Or at least:
Attention:
You have made changes to the photo.
If you rename the photo, any unsaved ...

If I crop an image and then rename it, the cropping is undone.

From my point of view, it should be the case that the cropping is retained.

My version is 1.8.3 64 bit (Windows)

yes,
I have just copied another jpg file into a new folder.
Then I made a copy of the jpg file and renamed it to .bak.
The problem has reappeared.

By the way:
My version is 1.6.2 64-bit (Windows)

I have two photos, one of which has the extension jpg and the other bak.
I call up the Compare function.
I then click on the delete icon to delete the photo with the bak extension. See red marking.
A prompt appears, which I confirm.
But the photo is not deleted afterwards.

It now works perfectly for new folders.
It also works if you go to "Create new thumbnails". See screenshot.
But the existing thumbnails are not updated automatically.

Thanks again for the bugfix.

Thanks for the very fast solution

As an idea or suggestion how this function could look like

In the end it would work similar to the already existing "Compare" function

You select two photos,
call the function
and then the window for the function appears.

On the left the photo is displayed with EXIF date.
When you press the ...

Thumbnails on folder icons are displayed in landscape orientation instead of portrait orientation when taken with iPhone.

Screenshot attached.

I can provide sample images or sample files from the iPhone, but they are too large to attach here.

I have installed the latest version
and then tested it four times.
The error did not occur again.
Hopefully it will not occur again in the future.

XnView changes the file names in the batch rename function.
The problem has been occurring for several years.
However, I have never been able to determine the exact cause until ...

Often additional image files are stored in a folder where the EXIF date does not match the rest of the photos, so the sort order is not correct.

Example:
Photos from a visit to a restaurant or museum:
I took photos of the visit (with correct EXIF date).
And I complete the collection with a scan of ...

It would be very helpful if the tool "change timestamp" (cmd_changeTime) could also be used in viewer mode.
Currently it can only be used in the browser.

the folder has in concreto 328 files

The problem seems to occur mainly when there are many HEIC files in a folder, so many thumbnails need to be created. It seems that the thumnails database has problems with too many HEIC files in a folder.

It might be a temporary solution if it would be possible to rebuild the thumbnails also for ...

thank you, it works fine
