I know of no reason why a developer would want to use a GtkImage widget.

They might use a GtkDrawingArea widget and use GdkRGB to handle
exposes on that, or they might use the GtkRGB widget that somebody
mentioned writing recently.

A search in the GNOME cvs repository turns up not one single application
using GtkImage. (The only references are its definition in GTK+, and
the suport in Glade)

So I wouldn't worry about that. Regards,
