Features

  • Supported platforms: Linux / Windows / Python 2.7.

  • Filters urls by regex.
  • Filters images by minimum size.
  • Scrapes through javascript popup links (limited support).
  • Live monitor window for displaying images as they are scraped.
  • Asynchronous i/o design using scrapy and twisted.
