hotspoticon out of scale when try to replicate demotour-weingut in html5 view

Hi,
sorry but i neet to solve another issue in my "pano clone" of demotour-weingut example.

When i force view of html5 visualization i have hotspot icons (sobstitute of polygonal flash hotspot in html5 visualization) completely out of scale and also if i set scale like this:

<style name="pichotspot"
capture="false"
zorder="1"
onclick="showpic();"
alturl="hotspots/zoomicon.png"
zoom="true"
scale="0.02" />

i obtain a very large icons.

i tried set to 0,01 but icons disappeared so 0.02 is minimum scale.

i try to attach screenshot with this set (0.02).

how solve this?

thanks
