The html page Gmap.htm contains a map 663x855 px, name GM003.jpg. The visible part of the map can be moved around inside the iframe by the scrollbars or arrow keys.
I would like to drag it with a mouse in a similar way to Google Maps. I've tried adapting the code on http://forums.asp.net/t/1267650.aspx/1
without success. Please could someone suggest correct code or point me in the right direction.
