Hi Frank,
One thing I've noticed, on the home page - the four flash objects for each visualizer do seem to load on Chrome browser and Firefox,
but not on Internet Explorer 11, the place-holders are not visible and the place where the pictures should be is blank / transparent.
It could be to do with compatibility with IE11, placement, z-index ranking in the html code, etc.
One thing to consider is maybe utilizing html5, with html5 natively rotating the images much like flash,
but in a more discrete and widely accepted format with a responsive layout overall for the whole site.
A responsive HTML5 script coded site would provide the huge advantage of being 100% mobile / tablet device compatible, for any screen size.
Thanks, hope this helps
Alf
