Hello @ailintom do you know if there is any plan to also use the orientation for JPEG files?

@seb-odoo JPEG files do not have an orientation tag comparable to the TIFF orientation tag. Unlike TIFF-files,

in JFIF files, the image orientation is always top-down

see https://www.w3.org/Graphics/JPEG/jfif3.pdf
JPEG files however can have EXIF tags, including the orientation EXIF tag, indicating the orientation of camera when shooting. You can transform the image according to the EXIF orientation tag using PIL by calling ImageOps.exif_transpose
