Including timeout in Node.js http.get while getting large number of image downloads

This is the code which I have been using to download images from URLs:

http.get(options, function (res) {
    res.on('data', function (data) {
        file.write(data);
    }).on('end', function () {
        file.end();
        console.log(file_name + ' downloaded ');
        cb(null, file.path);
    }).on('error', function (err) {
        console.log("Got error: " + err.message);
        cb(err, null);
    });
});

How can I add a timeout for every request so that it doesn't stay on waiting for a response which is either large data or unresponsive?
