PIL cannot read JPEG comment

[ganego]

What did you do?

I want PIL to read the JPEG comment (marker: 0xFF 0xFE).

I took an image with an attached JPEG comment - verified with exiftools & IrfanView to exist.

from PIL import Image, JpegImagePlugin
pic = Image.open(<path_to_pic_with_JPEG_comment>)
print(pic.info)

What did you expect to happen?

Show the JPEG comment in the dict.

What actually happened?

{'jfif': 257, 'jfif_version': (1, 1), 'dpi': (96, 96), 'jfif_unit': 1, 'jfif_density': (96, 96), 'exif': b'...'}

What are your OS, Python and Pillow versions?

• OS: W7x64
• Python: Python 3.8.1 x64
• Pillow: Pillow 7.0.0

I cannot attach an image via github ("Something went really wrong, ..."), so here is the file (5.61 KiB) (I downloaded it and verified it's byte-identical to the uploaded one):

It's not exposed under info right now, but could be easily added in https://github.com/python-pillow/Pillow/blob/master/src/PIL/JpegImagePlugin.py#L180

Yes, for the moment, you can access it through

from PIL import Image
im = Image.open("comment.jpg")
print(im.app["COM"])  # b'JPEG-COMMENT-TEST\x00'

I've created PR #4455 to resolve this.

Thank you both.
