Getting binary information with PyExifTool

[lolliffe]

I hope this isn't outside the scope of the forum, but I'll try.

In python, with exiftool installed, I can pull an MP3's binary image out, calling subprocess, e.g.

`proc = subprocess.Popen(['exiftool', '-Picture', '-b', sys.argv[1]],
                         stdout=subprocess.PIPE)
output = proc.stdout.read()
with open('out_pic.jpg', 'wb') as out_file:
    out_file.write(output)`
...and with PyExifTool installed, I can pull metadata, e.g.

`with exiftool.ExifTool() as et:
    make = et.get_metadata(sys.argv[1])['ID3:Artist']
    print(make)`
I could, but would rather not, use the subprocess way, of pulling the image, if I can do it with PyExifTool. But I haven't had any luck with something like:

`binary_string = et.execute('-Picture', '-b', sys.argv[1])`
or other variations, including when it erred out, telling me that the arguments needed to be byte strings, and trying things like  et.execute(byte('-Picture', 'utf-8'),..., where it stopped complaining, but gave me the result of b''.

If anyone has some guidance, especially if you've done this before, I'd appreciate the help.

Thanks in advance!

P.S.  Mods, if this needs to be moved to a more appropriate section, please feel free.

I am guessing that PyExifTool will run a sub-process anyway, so I would think that the first way you did it should be fine.
