This module extracts IPTC information from JPEG files. IPTC is (mostly non-technical) structured metadata about the image with fields like creator/artist, copyright, keywords, category, etc.
For more information, see: http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/#50577409_38034

Installing using npm:

npm install node-iptc

  var iptc = require('node-iptc')
  
  fs.readFile("myImage.jpeg", function(err, data) {
      if (err) { throw err }
      var iptc_data = iptc(data);
    });
