1. I'm not what you mean with playing with opacity parameter. My understanding form opacity is that with 2 layers, one is more or less shown as a background to the other. How would that translate back to not showing a certain area below the 5 images.
3. I found the example. And added the following CSS code into the module area:
DIV{$id}_wrapper DIV.ari-image-slider-wrapper .nivoSlider
{
-moz-box-shadow: none;
-webkit-box-shadow: none;
box-shadow: none;
}
But this doesn't remove the shadow. I guess I made a mistake somewhere?
4. See attached image within the red (partial) oval.
