Carousel, images stacking and not loading with firefox, mac

I checked your site on Firefox, Safari, and Chrome, and the pictures seemed to load properly.

If you still experience issues, could you please try clearing out your cache and cookies?

If you are not satisfied with the image loading times, you might want to try to activate the Photon module: it might help. You can read more about it here:

Hmmm… I cleared my cache and cookies and it still does it, with firefox on my windows machine looks fine but on firefox (4.0.1) on my mac it still looks odd, as if 2 or 3 images are layered one ontop of another.

I′ll look into photon as it sounds like a good idea.
