However you notice that the images/words donot fit as precisely as in the Javascript version. I plainly copied and pasted the elements from the baselayer to the slidelayers, so this is a internal Storyline issue that causes the position of Slidelayers to be somewhat off. Thus making it hard to get precise results...as you can see in the Review sample above.
Have fun with it...
