Zoom and Pan An Image In A Webrowser

[mike.hodgson]

Hi,

I have an image in a webrowser which is 3000 pixels wide so does not
fit in the browsers window. It is a CAD drawing so needs this detail.
Using the scroll bars makes the image difficult to view so I am looking
for some code where I can set the view width to 1000 pixels and the
code will allow me to zoom in and out of the image and pan it around
the page, a bit like how google maps works.

Can anyone help me with this please. It needs to work in firefox and
IE.

Regards,
Mike Hodgson.

http://jibbering.com/routeplanner/ has a basic implementation of
this, feel free to rip it off.
