Save images from chrome inspector/dev tools network tab

get-image-urls.js

/* open up chrome dev tools (Menu > More tools > Developer tools)
 * go to network tab, refresh the page, wait for images to load (on some sites you may have to scroll down to the images for them to start loading)
 * right click/ctrl click on any entry in the network log, select Copy > Copy All as HAR
 * open up JS console and enter: var har = [paste]
 * (pasting could take a while if there's a lot of requests)
 * paste the following JS code into the console
 * copy the output, paste into a text file
 * open up a terminal in same directory as text file, then: wget -i [that file]
 */

var imageUrls = [];
har.log.entries.forEach(function (entry) {
  // This step will filter out all URLs except images. If you just want e.g. just jpg's then check mimeType against "image/jpeg", etc.
  if (entry.response.content.mimeType.indexOf("image/") !== 0) return;
  imageUrls.push(entry.request.url);
});
console.log(imageUrls.join('\n'));

I don't understand what you mean by it takes a long time to paste? because when i paste, its instant then i get the message "undefined"

It occurs in situations where one needs to download a bunch of images.

update: we can also use charles or fiddler to proxy the chrome/firefox http traffic, then just select and save all image file to your cumputer, remember to add file extension like jpeg or png after that. It's effictive when you need download images with cookies. However this method won't keep the file order like what it is in Network Devtool panel.

an example python code for download image from har with cookies, inspired by @puziyi

import json
import requests

with open('source_har.har', 'r', encoding="utf-8") as f:
    har_json = json.loads(f.read())

for i,entry in enumerate(har_json['log']["entries"]):
    if entry["response"]["content"]["mimeType"].find("image/jpeg") == 0:
      url = entry["request"]["url"]
      name = str(i) + '.jpeg'
      cookies = entry["request"]["cookies"][0]
      # when cookies's value is boolean, you need convert it to str
      cookies = {k:str(v) for k,v in cookies.items()}
      img = requests.get(url, cookies=cookies).content
      with open(name,'wb') as f:
        f.write(img)

That worked on my windows10:

& 'C:\path\to\wget.exe' -r -nH --cut-dirs=<N> -P 'C:\Path\to\output' -i 'target_link.txt'

Thanks! saved me some time <3
if that comes to u " 'wget' is not recognized as an internal or external command"
Follow this ==> https://bobbyhadz.com/blog/wget-is-not-recognized-as-internal-or-external-command

in windows's instead of
"wget -i [that file]"
use following command from PowerShell:

Get-Content [that file] | ForEach-Object { Invoke-WebRequest -Uri $_ -OutFile (Split-Path -Leaf $_) }
