In the sample code when building GUI with UiBinder the following declaration
are very common--
xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
However now when we declare an Image,we do it as *ui*:image
field='logo' src='logo.png'/
why *ui
ui:image declares an ImageResource added to the implicit ClientBundle
generated by each ui.xml file (where the ui:data and ui:style are put too,
as DataResource and CssResource respectively).
If you want an Image widget, then yes, use a g:Image.
Note also, that ui:image are top level elements
