Welcome to the forums, Meeotch.Meeotch wrote: Sat Apr 18, 2026 5:47 pm Bumping this thread again. I also am a prior user of ACDSee and used that software to rotate images accordingly. In XnView, thumbnails are displayed with the original orientation (sidweways) but opening the photo displays it correctly. I have the same 3 settings selected as the above user. Is there a fix to this?
I'll try and help you... There's a lot going on with thumbnails, and quite a few ways for things to go wrong. In your case it's unlikely this is a bug, so it would have been better to simply make a new support/question post in the MP-General Support forum. This forum is for when you know you have a bug.
This thread is more than 3 years old, and the "above user" you referred to was asked to provide a sample file and then nothing more happened. So that situation isn't really helpful.
If you'd like to post (to some file sharing service) an unmodified image file that has the problem, we can look at it and help you understand what's going on.
There are a couple of other settings you need to check, in Settings:Thumbnail
-Use embedded thumbnail
-Create from original image...
Please report how those are set, along with the sample file.
Without understanding what's going on, you could simply enforce some corrective action on your own... On the Metadata menu, you'll see an option "EXIF Thumbnail". It has options to rebuild or force rotation of the thumbnail in the image. But whether your app displays it correctly depends on the settings above.
If the images have been modified since XnViewMP first scanned them, you might need to do a Metadata->Update Catalog from files, or execute "Rebuild Thumbnails" which is found in Settings:Catalog.
There's also a setting in Settings:Browser:Overlay Icons:Automatic Rotation. Enabling that doesn't actually rotate anything, but it enables an overlay icon to indicate if the application thinks the image needs automatic rotation. Turning that on will keep you better informed.
If you want more help, I'd suggest posting the sample image file and the settings...
