Thanks for the PR and sorry about the delay. The PR looks good but it will need a rebase. Also would be great if you can add a test and test image (with an open source license).

if hasattr(img, "_getexif") and callable(img._getexif):
exif = img._getexif()
elif "exif" in img.info:
exif = img.getexif()._get_merged_dict()

img._getexif() is an alias for img.getexif()._get_merged_dict() so we can probably switch to the public methods, which I think are supported since a long time ? (Our min version of pillow is 8.0 currently)

Gladly!
I just wasn't sure if I would break any weird combination, because both variants use some private API.
But let tox find out :-)

The extension list here and below should also include ".heif" I guess ?
Also, those extensions should be recognized only if pillow-heif is available, so might be better to store this list somewhere where it can be imported (in the image module ?) and reused.

I'm not sure about .heif files. As I understand it, this is more of a container format and may contain different image-formats.
I guess pillow-heif should be able to handle them all, but I have no way to test that yet.

I would actually prefer it if the program errors out if it encounters .heic images without pillow-heif installed, instead of just silently ignoring and skipping those pictures.
I mean, they are in fact Images - no matter if supported or not - and the user probably intended for them to be included in the gallery.
