A small note about the scaling function you wrote; it isn't ASP, ASP is server
side so if the user would press a button, the request has to do a trip to the
server and back to make it's effect visible, the code you posted is typically
client side scripting. So in that perspective IFRAME is probably acceptable.
Is is possible to call a function in another frame, in this case I would put
the image in the IFRAME with the above function. The zoom buttons on the main
page call the function in the frame to scale the image correctly.
Calling a function in another frame is done like this:
object.document.ImageZoom()
where 'object' is the reference to the frame.
