You can accomplish this with something like request and cheerio. For example:

var request = require('request'),
    cheerio = require('cheerio');

request(url, function(err, res, body) {
  if (err)
    throw err;
  var $ = cheerio.load(body);
  $('img').each(function(img) {
    console.log($(img).attr('src'));
  });
});
