Python Image Fetcher

A simple lightweight library to download images (and other files)

Install

With Python 3.5+ run:

pip install image-fetcher

Key features

• Speed: By using multi-threading, more images can be downloaded per second
• No download duplication: To avoid unnecessary downloads
• Progress bar: To track how your download is getting on

Usage

The simplest usage involves passing a list of URL's and the folder you want the images to be saved to:

from image_fetcher import multi_thread_image_download

multi_thread_image_download(
    ["https://benaandrew.github.io/images/sentiment.jpg","https://benaandrew.github.io/images/dog.jpg"],
    "images",
)

If you have your URL's saved in a text file you can instead give the path to that file

multi_thread_image_download(
    "urls.txt",
    "images",
)

Additional arguments

• max_fetching_threads (int): Sets the maximum number of concurrent image downloads
  • Increasing this increases download throughput but also uses more processing power and can cause errors when set too high
  • By default is set the number of cpu cores x 5
• download_timeout (int): Seconds before a download is abandoned
  • Increasing this means more time will be allowed per download. If every download is important you should set this high
  • If set to None, download will only timeout if the connection does so
  • The default is 5 seconds
• verbose (bool): Whether to show progress bar
  • On by default

You can pass these like so:

multi_thread_image_download(
    "urls.txt",
    "images",
    max_fetching_threads=5,
    download_timeout=10,
    verbose=False
)
