Comment:
Here is [https://github.com/python-
pillow/Pillow/issues/4703#issuecomment-645219973 another Pillow issue]
that may be of interest. It seems that Pillow ignoring the EXIF
orientation is by design. Pillow is used in various contexts, not just
web. I think in other cases it may make sense to return the dimensions
without considering the EXIF orientation. But the web defaults to
considering the EXIF orientation (see
[https://chromestatus.com/feature/6313474512650240 this link]). Since
Django is for the web, I think it should consider the EXIF orientation. I
was able to make a quick and dirty fix to django/core/files/images.py. I
added the following right above where it says `return p.image.size`
([https://github.com/django/django/blob/3.2.15/django/core/files/images.py#L77
source]):
{{{
try:
exif = p.image._getexif()
except (AttributeError, ValueError):
pass
else:
if exif is not None and exif[274] > 4:
return (p.image.size[1], p.image.size[0])
}}}
