Problem converting Visio files to HTML

[yjs]

I have a large Network Diagram inluding CISCO stencils (blue icons round with four arrows for routers and switches and firewall)when I convert the file to a HTML format, I loose some of my router/switch icons.
I have tried to save in a GIF JPG format with no success.
I have a problem with some of my colleague that require to view the file, the visio viewer does not follow the hot spot properly. That is why I want to save my drawings to HTML and then use HTML hot spot and hyperlinks.
On a different issue as my drawing is quite large A1 size. I would like to be able to ZOOM IN and OUT in HTML. Does any body know of a tool to be able to zoom in and out.

Thanks in advance Cheers YJS

I'm not exactly sure about why your diagram is losing items, but I hope I can shed some insight on the zoom issue. I use Visio 2002 Pro, and I save my floorplan/network layout in HTML just using the Save As function. When I view the page, there's a zoom dropdown in the bottom right corner.

If you're using 2002, it should be a no-brainer, but this is an MS product, so there's always a possibility of some quirk that jsut doesn't work for you.
