This is the patch for file Image.py:

import re

def sanitize_filename(filename):
    invalid_chars = r"[<>:\"/\\|?*]"  # Expand with other bad chars if needed
    new_filename = re.sub(invalid_chars, '_', filename)  # Replace with underscores
    return new_filename

Inside your save function

filename = sanitize_filename(filename)
fp = builtins.open(filename, "w+b")
