Help please - website interactive tour

Hello,

I am looking to make an interactive website tour which shows different features of a web site.

The first page of the tour would be an image of the front page of the site with a menu of features off to one side. The menu items would be pulled from an XML document.
Clicking on certain parts of this image or the menu items would load a new image with links and information about the features of the page.
It would also be nice to have visible hotspots so users know what parts of the image they should click on, and perhaps have them highlight when hovering over menu items.

The data including links, explanation text, and image locations would be stored in an XML document so it is easy to edit.

I cant find an example of exactly what I want, but these sites have some of the features I am looking for…
http://www.contactenergy.co.nz/web/view?page=/contentiw/pages/shared/sampleonlinebillflash&vert=ob - this one is pretty
close to what I am after.

http://www.kirupa.com/web/xml/examples/squirrelfinder.htm - this example has a menu created by XML.

Any ideas or suggestions? Anyone know of any tutorials like this?

Thankyou!

Thanks small_guy. You’re right, after searching around and looking at code and samples I have realised that this is a big complicated job (thanks for the link too - some handy info there).

If I find any more useful samples I’ll post them here in case there are any other (insane) people out there interested in doing the same sort of project.
