The provided content does not contain an actual news article but rather consists of website registration and login form elements. Without access to the original article text about the Petit Noël exhibition at Callander's Alex Dufresne Gallery, it is not possible to create a complete and detailed rewrite that would include essential information such as exhibition details, featured artists, opening dates, gallery location, or curatorial information.

To properly fulfill this request, the actual article content about the gallery exhibition would need to be provided rather than the website's user interface elements.
