Hi Amit,
Have a look at my application called giv, which does exactly this
(except for the dragging part). It is built around my widget
GtkImageViewer, which you can also use yourself if giv isn't general
enough for you.
Have a look at:
http://imagic.weizmann.ac.il/~dov/freesw/gtk/gtk-image-viewer/
and
http://imagic.weizmann.ac.il/~dov/freesw/gtk/giv/
Note that both the widget and the standalone tool are being developed
in the gnome cvs.
Regards,
Dov
