Node Image Downloader

A Node module for downloading image to disk from a given URL

Install

npm install --save image-downloader

Options

• url (required) - the image URL to download
• dest (required) - the image destination. Can be a directory or a
  filename. If a directory is given, ID will automatically extract the image
  filename from options.url (see usage bellow)
• extractFilename - boolean indicating whether the image filename will be
  automatically extracted from options.url or not. Set to false to have
  options.dest without a file extension for example. (default: true)
• headers - HTTP headers (default: {})
• timeout - milliseconds before a request times out

For advanced options, see Node.js http.request()'s options documentation
