How to Change the Source of MultiScaleImage at Runtime?

Hello Daniel
I'm working on a FLASH site that should use the MultiScaleImage.
I want to make a template for loading different zoom-images, but I have several problems:
I cannot implement it in Flash. I just can make a Flex swf and load it into Flash...
I dont want to make a Flex swf for each zoom-image. I just want to make a Template, load it into Flash, set the XML descriptor and init it.

I can load it into Flash and access the component, but when trying to set the XML descriptor, it not reloads the new XML configuration.

Is there a way to change the zoom-image on the fly?

I've read that the system works in both Flash and Flex but I've not finded the Flash component, (just the Flex one)
Is there a way to implement it in Flash directly (not Flex)

Thanks in advance....
