Hover effect on slideshow images

Hello to all,
Is there a way to set a custom image while hovering the slideshow images. It is not pre built, I asume?
What CSS do I need to achieve this then?

Thanks,

Paul

Hi
I don't understand your request, a slideshow show several images sliding. Can you please explain your request ?
(and no, this is not pre built)

Hi, I'll try to make myself clear. What I want is this (see attachment)
Hovering the image shows image effect. What line of CSS is needed for that?

Paul

ok, this is not something that is really related to Slideshow CK ...
this is only some css customization specific to your project

You could try to use the :after or :before pseudo class to add an overlay on mouseover.
