Is there a way to fetch the contact image(PhotoURL) from the salesforce Org and convert to base24 format?

Can anyone help me solving this, I’m trying to fetch contact image from the salesforce DB and how can i download and convert it to base24 format…?

var queryString = "Select PhotoUrl from Contact where Id = '" contactid + "'";
	return conn.query (queryString)
	.then (function(resultSet) {
		var cont_act = resultSet.records;
               return conn.chatter.resource(cont_act[0].PhotoUrl).retrieve();
	}) .then(function(result){
          //return some encrypted data how do I decrypt this
      })

The photo url will only contain the url ,you have to use the request module to make a call and get the image .
