Adds user location request to upload GPS coords

[frgfm]

It would be much more accurate to request access to the user location upon uploading to get the most accurate information about the location where the picture was taken.

from exif import Image

img = Image("path/to/img.jpg")
if img.has_exif:
    cam_maker = img.lens_make
    cam_model = img.lens_model
    cam_specs = img.lens_specification
    pic_ts = img.datetime
    pic_ts_offset = img.offset_time

Using metadata with PIL 9:

from PIL.ExifTags import TAGS
from PIL import Image

img = Image.open('IMG_1135.JPG')

meta = img.getexif()

for tag_id in meta:
    print(TAGS.get(tag_id), meta.get(tag_id).decode() if isinstance(meta.get(tag_id), bytes) else meta.get(tag_id))
