with open(f"{cid}.jpg", "wb") as f:
    f.write(photo_data)

# Exit program
sys.exit()

For python3 you can just do the following to get the photo writing correctly

Update the thai2unicode method

def thai2unicode(data):
	if isinstance(data, list):
		return bytes(data).decode('tis-620').strip().replace('#', ' ')
	else :
		return data

Replace the line with HexListToBinString with the following

data = bytes(photo)

@bouroo Thanks for this, it has been very helpful.

Thanks for your code.
I tried this on python3. it doesn't work on reading profile picture.
I changed some code of you then it works.
