How to give a click function for center | focus image in roudabout carousel?

I am trying to give click function to focus image (center image) in jquery round about carousel .

http://fredhq.com/projects/roundabout/demos/images in this url I need click fucntion which should go to other web page.
I need this function only for center(focus) image not for other child images . For other image it should come in focus and then I need click even to happen.

For example :

On click of the center or focus image I need to go to (open new window) google.com

questions :

1) Is there any way to call a onclick event for focus image ?
2) If its not possible through roundabout carousel is there any other carousel which supports this.
3) http://fredhq.com/projects/roundabout Is there any API I can use for this on click event?

Can Anyone help me in this
