recursive image download with requests

Question

I am trying to download images from openi (https://openi.nlm.nih.gov/index.php) using python 3.5 and requests. I am using their rest API as follows:

resp = requests.get("http://openi.nlm.nih.gov/retrieve.php", 
       params = {"query":"Feulgen", "m": 1, "n": 12})
print(resp.content)

This gives me a json file that contains textual information about the images that I would like (including their .png filenames) but I would really like to download the images themselves.

Do I have to download each image according to the specific url listed in the JSON or is there a way to do some sort of "batch download" for the images that would come up in this query?

I have seen this post about downloading images with requests but it seems that I need the .png or .jpeg or .whatever URL. Does anyone know way to get the images without the individual image URLs?

Thanks in advance.

yes..you have to call image download function for each URL intended — Morse, Mar 20 '18 at 19:30

Yes just through and save !

import requests, pprint
resp = requests.get("http://openi.nlm.nih.gov/retrieve.php",
       params = {"query":"Feulgen", "m": 1, "n": 12})
for i in resp.json()['list']:
    #pprint.pprint(i)
    pprint.pprint(i['imgLarge'])
    img = requests.get('http://openi.nlm.nih.gov/'+i['imgLarge'])
    if img.status_code == 200:
        with open("/tmp/"+img.url.split("/")[-1], 'wb') as f:
            f.write(img.content)
