On odoo.sh, in some circumstances, when uploading an image as attachment in odoo leads to a blank image thumbnail. The same image was successfully uploaded in the same odoo version on runbot instance. After some investigations, it appears that the issue comes from the python-pillow version used. A few bugs exists [0,1,2] in python-pillow 7.0.0 (packaged in ubuntu Focal) that are now fixed in version 8.1.0 [3,4,5] (packaged in Debian and specified in Odoo requirements.txt), that causes the `ImageOps.exif_transpose` method to fail. The present issue can be considered as a corner case as only images with particular exif tags cause the issue. The present fix is a simple workaround by first checking the presence of the orientation tag and using it, we can avoid a call to the `exif_transpose` method. opw-2369166 [0] python-pillow/Pillow#4346 [1] python-pillow/Pillow#3973 [2] python-pillow/Pillow#4238 [3] python-pillow/Pillow#4637 [4] python-pillow/Pillow#3980 [5] python-pillow/Pillow#4009

The
Image.Exifclass currently uses the legacyImageFileDirectory_v1. This PR changes it to useImageFileDirectory_v2.Aside from the good practice of moving away from a legacy class, it also changes RATIONALs to be read as IFDRationals, instead of a tuple with (numerator, denominator).
A warning when saving tags 282 and 283 has been reported here and here, that the tags
had too many entries: 2, expected 1. This PR means that only one value, the IFDRational, will be attempted to be saved, instead of two values, a tuple of the numerator and the denominator.
