Beautifulsoup - How to open images and download th

问题:

I am looking to grab the full size product images from here

My thinking was:

• Follow the image link
• Download the picture
• Go back
• Repeat for n+1 pictures

I know how to open the image thumbnails but not how to get the full size images. Any ideas on how this could be done?

This will get you all URL of the images:

import urllib2
from bs4 import BeautifulSoup

url = "http://icecat.biz/p/toshiba/pscbxe-01t00een/satellite-pro-notebooks-4051528049077-Satellite+Pro+C8501GR-17732197.html"
html = urllib2.urlopen(url)
soup = BeautifulSoup(html)

imgs = soup.findAll("div", {"class":"thumb-pic"})
for img in imgs:
        print img.a['href'].split("imgurl=")[1]

Output:

http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g1_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g4_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g2_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g5_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g3_satellite-pro-c850.jpg

And this code is for downloading and saving those images:

import os
import urllib
import urllib2
from bs4 import BeautifulSoup

url = "http://icecat.biz/p/toshiba/pscbxe-01t00een/satellite-pro-notebooks-4051528049077-Satellite+Pro+C8501GR-17732197.html"
html = urllib2.urlopen(url)
soup = BeautifulSoup(html)

imgs = soup.findAll("div", {"class":"thumb-pic"})
for img in imgs:
        imgUrl = img.a['href'].split("imgurl=")[1]
        urllib.urlretrieve(imgUrl, os.path.basename(imgUrl))
