Rying to reuse a loader, receiving an error

I want to reuse the same loader to cycle through a list of images that will be placed in a rotating banner. My code can be found here:

The error I am getting is the following:

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::Loader/_load()
at flash.display::Loader/load()
at banner_fla::MainTimeline/loadBanner()
at banner_fla::MainTimeline/loaded()

Is there anything that seems offensive in there?
