Yes, this would work ... once you've converted your autocad drawing or
postscript image to an enormous highly detailed GIF (postscript to GIF is
always a fun conversion) ... once you've ensured that all of your users are
running a current version of IE so that the VB script will work (too bad for
Netscape users) ... and once you've compelled your users to endure a very long
download to get the image onto their local system ... and once they've figured
out the click/double-click semantic ...

Of course you wouldn't have to worry about these issues with a PDF, but Mike's
right, you could do it with an HTML file and a GIF image.
