--- Comment #3 from Frédéric COIFFIER <frederic.coiffier at free.fr> ---
I haven't enough information about parameters used with the piwigo exporter but
I think that I reproduce the problem.

If "Resize photos before uploading" is NOT CHECKED :
 * The TIFF file is uploaded but cannot be displayed by Piwigo : Piwigo bug as
I'm not sure it is able to display 16-bits TIFFs

If "Resize photos before uploading" is CHECKED :
 * The Piwigo exporter converts the TIFF in JPEG (with a rescaling) but the
EXIF Orientation seems not used during the conversion.

The conversion is done with a QImage :
QImage image;
...
image.load(mediaPath);
...
image.save(m_path, "JPEG", quality);

I don't know if QImage can convert a TIFF to JPEG by preserving the EXIF
Orientation.
