python save image from url

Question

I got a problem when I am using python to save an image from url either by urllib2 request or urllib.urlretrieve. That is the url of the image is valid. I could download it manually using the explorer. However, when I use python to download the image, the file cannot be opened. I use Mac OS preview to view the image. Thank you!

UPDATE:

The code is as follow

def downloadImage(self):
    request = urllib2.Request(self.url)
    pic = urllib2.urlopen(request)
    print "downloading: " + self.url
    print self.fileName
    filePath = localSaveRoot + self.catalog  + self.fileName + Picture.postfix
    # urllib.urlretrieve(self.url, filePath)
    with open(filePath, 'wb') as localFile:
        localFile.write(pic.read())

The image URL that I want to download is http://site.meishij.net/r/58/25/3568808/a3568808_142682562777944.jpg

This URL is valid and I can save it through the browser but the python code would download a file that cannot be opened. The Preview says "It may be damaged or use a file format that Preview doesn't recognize." I compare the image that I download by Python and the one that I download manually through the browser. The size of the former one is several byte smaller. So it seems that the file is uncompleted, but I don't know why python cannot completely download it.

Solution 1

A sample code that works for me on Windows:

import requests

with open('pic1.jpg', 'wb') as handle:
    response = requests.get(pic_url, stream=True)

    if not response.ok:
        print(response)

    for block in response.iter_content(1024):
        if not block:
            break

        handle.write(block)

Solution 2

import requests

img_data = requests.get(image_url).content
with open('image_name.jpg', 'wb') as handler:
    handler.write(img_data)

Solution 3

It is the simplest way to download and save the image from internet using urlib.request package.

Here, you can simply pass the image URL(from where you want to download and save the image) and directory(where you want to save the download image locally, and give the image name with .jpg or .png) Here I given "local-filename.jpg" replace with this.

Python 3

import urllib.request
imgURL = "http://site.meishij.net/r/58/25/3568808/a3568808_142682562777944.jpg"

urllib.request.urlretrieve(imgURL, "D:/abc/image/local-filename.jpg")

You can download multiple images as well if you have all the image URLs from the internet. Just pass those image URLs in for loop, and the code automatically download the images from the internet.

Python code snippet to download a file from an url and save with its name

import requests

url = 'http://google.com/favicon.ico'
filename = url.split('/')[-1]
r = requests.get(url, allow_redirects=True)
open(filename, 'wb').write(r.content)

Solution 5

import random
import urllib.request

def download_image(url):
    name = random.randrange(1,100)
    fullname = str(name)+".jpg"
    urllib.request.urlretrieve(url,fullname)     
download_image("http://site.meishij.net/r/58/25/3568808/a3568808_142682562777944.jpg")

That's perfect! Thank you so much! I don't know why requests module could complete that while urllib and urllib2 cannot do that, but anyways.

@vlad what if we are not aware of the image extension from the URL but we know it is an image?

[Vlad Bezden]

@MonaJalal you don't have to specify an extension, as long as you have valid qualified URL address.

[Max Vollmer]

Welcome to Stackoverflow and thanks for your contribution! Could you add an explanation to your answer what the code does and why it works? Thanks!

How do I add the headers for url in urlretrieve? I had a problem with images opening in the browser but not through code using urlretrive. I have tried urlopen but I don't know how to download the image using urlopen.

pip install requests if you don't have

[Felipe Toledo]

Using '.content' after requests.get() is the key to save an image

That gives me an empty image for the following URL: genome.jp/pathway/ko02024+K07173 Any idea how to fix this?

[Cleb]

It does not work for the following URL; any idea how to fix it? genome.jp/pathway/ko02024+K07173

@Cleb That's not an image

[RAZ0229]

@Cleb That's because the url you provided doesn't belong to an image. Try it with url1 = 'https://www.genome.jp/tmp/mark_pathway1641220140108369/ko02‌​024.png' in this case

@VladBezden - This saves the image to a folder, but when I open the image it says that windows does not support the file format, despite it being a simple jpg. Do you know why?

I tried this but I get an error: HTTPError: Forbidden. Do you know why this is? I'm using this URL: assets.ellosgroup.com/i/ellos/ell_1682670-01_Fs.
