Sending an image through YARP from a web browser fails

[nunoguedelha]

The problem is with the object type check in the yarp.Image class copy method:

• For starters there is a bug in the _image.copy wrapper method:

    _image._copy = _image.copy;
    _image.copy = function (obj) {
        if(_image.getObjType == obj.getObjType)
            _image.copy(obj);        <------------------- HERE
        else
            console.log('Error: impossible to copy image');
    }

  _image.copy(obj) should be _image._copy(obj) for calling the original copy method, otherwise we create a infinite loop recursive call.

• Sending an image sample through YARP from the browser is not properly implemented in the yarp.js package. The problem is bigger than just the object type check failure described earlier. I've opened an issue on yarp.js repo.
