Since IPTC metadata seems to be less commonly used than EXIF metadata, a compromise might be grabbing the ImageDescription EXIF metadata entry with Pillow.

This requires only a few lines of code:

# -*- coding: utf-8 -*-
import sys, os
from io import BytesIO
from PIL import Image

def run(bk):
    imgdata = bk.readfile('Image1219.jpg')
    img = Image.open(BytesIO(imgdata)).convert('L')
    image_description = None
    exif = img.getexif()
    # 270 = ImageDescription
    if exif and 270 in exif:
        image_description = exif[270]
        print(image_description)

    return 0

def main():
  print ("I reached main when I should not have\n")
  return -1

if __name__ == "__main__":
  sys.exit(main())

The code will return the string: A Prince looks out between the bars of a prison window.
(It refers to this image provided by the OP.)

IMHO, automatically extracting some human generated description with Acess-Aide is better than extracting no description at all.

@oston would extracting the ImageDescription information be helpful to you?
