Incorrect maker notes offsets

[marciano]

Hello,
I receive photos from people to show in a site.
To display a link to see localization I use
exiftool -gpsposition /path-to-file/
In some isolated cases I see in httpd log file errors like
Warning: [minor] Possibly incorrect maker notes offsets (fix by 14?) - /path-to-file/
Warning: InteropIFD pointer references previous PreviewIFD directory  - /path-to-file/
It does not affect image display but maybe there's a way to avoid such kind of errors.
Thank you

You can avoid the errors by not editing the images with buggy software.

You can suppress the warnings by using the exiftool -m option.

You can fix the errors by using ExifTool to write something to the file with the -F option.

See FAQ number 15 for more information.

Thanks Phil for your reply.
Regrettably, these photos are not mine. Users upload them into my site.
I only use Photoshop and Bridge to manage metadata.
Thank you.

You won't get this problem with Adobe products because they kill the maker notes completely.  Much worse than the buggy software which at least attempts to preserve this information.

I wish more people would report things like this.
