Image files provided by rest-fs become unreadable. The same may happen with all other binary types.

On the file fileserver.js, replace:

  fileDriver.readFile(filePath, encoding, function(err, data) {

by:

  fileDriver.readFile(filePath, null, function(err, data) {

... then the file transmission works.

Well, the problem comes from the default encoding:

  var encoding = req.query.encoding || 'utf8';

Is this really necessary?
