XnView Software

Hi, I'm Rolf and I'm new to this forum.

I'm using XnView MP 1.6.4 on a MacBook Air M1 running macOS Sonoma 14.2.1

After modifying various JPEG photos, the thumbnails are no longer displayed in XnView, even though the file is not corrupted. Only as a preview JPEG. Recreating miniatures was also unsuccessful. The photos are stored on an external hard drive. This is my question. How can I restore the miniatures?

when you click on the files, do you have the preview?

Yes, the preview from Mac

i means preview in XnView

Preview in XnView doesn't work

Preview in XnView does not work. When I click on the photo in XnView to preview, the preview from the Mac automatically opens.

could you send me the file?

Thank you for your support and help. After yesterday's macOS update from Sonoma 14.2.1, the error in XnView MP is no longer traceable. Thumbnails are now displayed correctly again. Thanks again.
