ExifImage.js source code （line 116)

  var self=this;
  setImmediate(function() {
    self.loadImage(ops.image, function (error, exifData) {
      if (error) {
        return callback(error);
      }
    
      callback(null, exifData, ops.image);
    });
  });

setImmediate method is not expected to become standard, and is only implemented by recent builds of Internet Explorer and Node.js 0.10+.
Reference: Window.setImmediate()

To be compatible with more browsers, change to:

  var self=this;
    function _loadImg() {
        self.loadImage(ops.image, function (error, exifData) {
            if (error) {
                return callback(error);
            }

            callback(null, exifData, ops.image);
        });
    }
  try {
      setImmediate(_loadImg);
  }catch (e) {
      setTimeout(_loadImg, 0);
  }
