Is there a way to access the creation time of the images? By this one could wait 3 hours before downloading a new file.
Currently the images do not contain EXIF data and the server response with this header:
t = 'https://clouds.matteason.co.uk/images/2048x1024/clouds.jpg'
response = requests.head(t, allow_redirects=True)
print(json.dumps(dict(response.headers), indent=4))

}Date is the time of downloading and last-modified seems to change every 30 minutes. It would be best, if this information were available in the header sent by the server. Of perhaps in a separate text/json file on the server.
