Sorry that the title wasn't very clear, basically I have a list with a whole series of url's, with the intention of downloading the ones that are pictures. Is there anyway to check if the webpage is an image, so that I can just skip over the ones that arent?

Thanks in advance

You can use requests module. Make a head request and check the content type. Head request will not download the response body.

import requests
response = requests.head(url)
print response.headers.get('content-type')
