[HELP] img grabber script - Bestandsextensie - Oct 26, 2018

hi there, i wanted to fill up my folder with some good HighResolution pictures nam sayin so i created this script the thing is on the site theres two links one thumbnail and one full resolution, it grabs both.

so i am asking for a way to not get duplicates and explain it please, feel free to use this script if u dont care about duplicates or use it yourself

becareful it grabs every url that has an image on it ending with .jpg

on the site i targeted the thumbnail = 123.jpg thats can pop up but the real link also redirects to 123.jpg so i get two values

Code
import requests
from bs4 import BeautifulSoup
from random import randint



def imageGrabber(url):
   req = requests.get(url)
   soup = BeautifulSoup(req.content, 'html.parser')
   images = soup.findAll('a', href=True)
       
   for img in images:
       img = img.get('href')
       if img.endswith('.jpg'):
           f = open(str(randint(0,999))+'.jpg','wb')
           img = 'https:'+img
           print(img)
           f.write(requests.get(img).content)
           f.close()
           

def main():
   imageGrabber('')
   
   
if __name__ == '__main__':
   main()

to use it add an url from a 4chan thread in the imageGrabber function in main. i cant add urls yet so

Yeah I don't know why are you getting 2 copies, didn't try your code but here is a little improvement I want to make.

Code
import requests
from bs4 import BeautifulSoup
# from random import randint ##NOPE!
from itertools import count

c = count(0)



def imageGrabber(url):
  req = requests.get(url)
  soup = BeautifulSoup(req.content, 'html.parser')
  images = soup.findAll('a', href=True)
     
  for img in images:
      img = img.get('href')
      if img.endswith('.jpg'):
          with open open('{}.jpg'.format(next(c)),'wb') as f:
              img = 'https:'+img
              print(img)
              f.write(requests.get(img).content)
 
 
if __name__ == '__main__':
  imageGrabber('') #Don't need a main function

Hope it help a little bit!

Here you go buddy no more duplicates:

Code
import requests
from bs4 import BeautifulSoup
from random import randint


def imageGrabber(url):
    imgList = []
    req = requests.get(url)
    soup = BeautifulSoup(req.content, 'html.parser')
    images = soup.findAll('a', href=True)

    for img in images:
        img = img.get('href')
        if img.endswith('.jpg'):
            if not img in imgList:
                imgList.append(img)

    return imgList
def saveImages(list):
    for img in list:
        f = open(str(randint(0, 999)) + '.jpg', 'wb')
        img = 'https:' + img
        print(img)
        f.write(requests.get(img).content)
        f.close()

def main():
    list = imageGrabber('http://boards.4chan.org/k/')
    saveImages(list)

if __name__ == '__main__':
    main()

and enjoy getting your IP banned. Should have tricked any website with giving user-agent and fake browser.

There is a wonderful 4chan api wrapper for this
