Hi Klaus,
It's easier to show you than try to explain.
http://www.projectsolutions.es/demos/yomec/tour.html (takes a while to load as I'm still working on stuff)
As the tour opens, there are two animated hotspots visible.
The one on the left opens an image in the manner that I would like but does not scale to the stage width or height.
The one on the right opens an image which scales to stage width and height but opens in the way described in my previous post.
Thanks for your time.
