Requested in #8787 (comment) - a note in the documentation that JpegImagePlugin's info["comment"] is from the COM marker

Pillow/src/PIL/JpegImagePlugin.py

Lines 173 to 179 in bcdb688

def COM(self: JpegImageFile, marker: int) -> None:
#
# Comment marker. Store these in the APP dictionary.
n = i16(self.fp.read(2)) - 2
s = ImageFile._safe_read(self.fp, n)
self.info["comment"] = s

and that this is distinct from the UserComment EXIF tag.

Pillow/src/PIL/ExifTags.py

Line 157 in bcdb688

UserComment = 0x9286
