A Node.js module for downloading a single image or multiple images to disk from a given Url (checking if urls exist and detecting image type)

Prerequisites

$ npm install images-downloader --save

Or you can clone and install HEAD:

Usage

const download = require('images-downloader').images;

// The file will be downloaded to this directory. For example: __dirname + '/mediatheque'
const dest = 'path/to/dest'

// An array of image(s) to download
const images = ['http://url.com/image1.jpg',
	'http://url.com/image2.png',

To download your single or multiple images use the following...
