Title: Find images with wrong exif orientation
Post by: ben on March 04, 2017, 12:54:55 PM
Hi everyone,

before i started to use iMatch, i used to rotate images using the builtin windows image viewer.
Unfortunately, this rotated the image but not the thumbnail and not the exif:orientation.

Is there a way to find those images?

Though my hopes are not too big...

Thanks,
Ben

As a general rule: The built-in tools in Windows are super-basic and often produce problems. Don't use them. So many users fall for that...

There is no automated way to tell if the image data has been rotated independently from the EXIF orientation and/or thumbnail.
Except for manual inspection.

Maybe it you open the in in Ps or whatever editor you use and re-save them the problem is solved. You can tell Ps to ignore Exif orientation and when it saves the image it will write the image data and thumbnail in the same orientation.

Sigh, i was expecting that.
But thanks for clarifying.
