Python Help - Downloading Images from URL

I'm pretty new to python but I'm using the following script to download images from links that live in the attribute table of my layer.

import arcpy import urllib.request import os # Set the workspace arcpy.env.workspace = r"C:\workspace\GIS.gdb" # Define the feature class and the fields fc = r"C:\layer_zip.shp" fields = ["image_url", "id"] # Define the output directory output_dir = r"C:\Users\download" # Loop through each row in the feature class with arcpy.da.SearchCursor(fc, fields) as cursor: for row in cursor: photo_url = row[0] object_id = row[1] # Construct the file name using the OBJECTID or another unique identifier photo_filename = os.path.join(output_dir, f"{object_id}.jpg") # Download the image from the URL and save it to the output directory urllib.request.urlretrieve(photo_url, photo_filename) print("Photos have been downloaded and saved.")

It will download several photos before I get this error message

URLError                                  Traceback (most recent call last)

Any help is appreciated!

I would suggest running the urllib.request in a try statement, that way the script doesn't hang on a single picture, and you can see if it is just one url or all of them that are problematic:

# Download the image from the URL and save it to the output directory try: urllib.request.urlretrieve(photo_url, photo_filename) except URLError: print(photo_url)
