EXIF image roatation

Hello

I noticed that XnView does not autorotate all the images.
For example there is this one.
Image
Neither the thumbnail nor the picture are rotated.
Other software like MS Picture and Fax Viewer or MS Office Picture Manager do it correctly while IrfanView for example does not.
The picture was taken using a Canon Powershot A510
Is there any setting that i have overlooked?

Thank you

It is also possible that the image is normal ( as far as i remember this should be true) and the software autorotates it although it should not.I get the feelings that this is the cause especially since programs like Paint that do not have EXIF options also open it correctly.

Thanks

I took a screenshot of my desktop.
Maybe the EXIF got lost because of the upload ..i don't know :|
if you look at the thumbnail for IMG_5502 you will see that it is rotated
although it should not.
Also 5490 , 5491 are the same

Ok, i've received your picture.
The problem is your pictures for me, there is a EXIF orientation (6-right/top) so the picture must be rotated.
You can disable EXIF rotation in Option/General

this is a bit unfortunate.
I started to really like XnView.
Anyway i checked a bit and it seems the other programs that open it correctly do so because they do not apply EXIF rotation at all.
IrfanView also shows it incorrectlysince it has EXIF rotation capability.
Maybe my camera has some problems.
Anyway...thanks for the help.

Yes, must be something with the camera. From my experience, orientation sensors have problems when photographing downwards, this might apply in your above picture. Some digital cameras display the orientation they recognize in the monitor display (small arrow which points to the top), so perhaps you can try a bit and see what the camera "thinks" is the top.
