You can only use widgets (<g:Whatever>) as direct children of other
widgets, or descendants of <g:HTMLPanel> widgets.

Where the hell have all of you been seeing this code to add widgets to
the page? Widgets should be children of other widgets, except for two
cases: RootPanel/RootLayoutPanel, and those widgets created by their
wrap() static method.
In your case:
RootPanel.get().add(test);

If you want to have an Image widget as a component of your
BinderUiTest object, you have to turn it into a Composite (probably
using an HTMLPanel widget as the root object).
