Image Loader

Load all images from given url.

Usage

usage: imageloader.py [-h] -u URL [-D DIR] [-d]

optional arguments:
  -h, --help         show this help message and exit
  -u URL, --url URL  URL to read
  -D DIR, --dir DIR  Write images to specific directory
  -d, --debug        Display debug messages

Python version 2.7 or later is required (works with python 3).

Option -D DIR is optional, the default location is ./saved-images.

Running

Just execute the script with -u URL parameter, for example

$ python ./imageloader.py -u http://www.google.com

This will read the specified URL (http://www.google.com in this case) and save every image it can scrape from the html and download to directory saved-images. Download directory contains a list of downloaded files (filelist.txt).

Running the test suite is done by running the test file

$ python ./test_imageloader.py

Code is tested in Arch Linux with python 2.7, python 3.6 and pypy 5.6. Code is checked with pylint 2.0.0 (Python 3).

Required libraries are beautifulsoup4, requests and lxml.

Limitations

Images with element containers are not supported as they are much harder to assemble together than traditional elements.

Embedded base64 encoded images are not supported.

Excepts given url is reachable with status code 200. Redirected urls are not tested and may not work.

Images are saved with their original names which could be messy.

Image directory structure is not preserved, all images are saved in one directory flat.

Generated download log ('filelist.txt') is not sorted.

Network throttling in url verification is very rudimentary (random sleep between 50-500 ms) and does not work properly with python 2. Image download does not have throttling at all.
