That means i am the first one.

Sorry for my english - its not my motherlanguage.

I have the problems also with simpleviewer. There is a blank site on Android. On all Windows browsers it works well also on IOS. I use the lite version of simple viewer- I thought juicebox would be the right  thing as it should work on andriod also in the lite version - but it does not.

The demo of your sites works on my android.  But the generated index.html does not

You can test it f.e. here: www.hurricaneproject.at/media/_gallery_neu/index.html

Does it mean its the same with simple viewer - they both run only in the pro versions on android platforms?
