xara web designer 11 and background slider

i am using xara web designer 10 premium
and used java to make background slider for my site
http://www.agriturismomadonnina.com/
in web designer 11 it is possible to use a full screen background slider like the one i created?
i tried the code of my site in wd 11 and it works only in browser not in xara preview
but after publishing it works.
the italian site
http://www.agriturismomadonnina.it/
is exported with version 11 -the preview show a blank site
I tried the trial version and can not download the new slider

The slider is working for me on your second link.

The second site loads fine, but.. ..slowly.

There are a lot of images and when I ran a performance analyser, many images are taking between 1 and two seconds to load, EACH. This gives the impression of a blank site until they are all ready. It took over eleven seconds to load completely.

I think the largest images are about 100Kish, so not that big.
