Use avatar from file or url

Okay then.

Can you turn this:

The question is vallidate and use the url if the user havent selected a file but for that i should remove the avatar callback.

.. into a question then?

And maybe explain what performance concerns you have?

It seems to me that you'll have a POST that contains either a populated URL field, or an unpopulated URL field. I don't see any complexity in checking if the URL field is populated.
