Adding random feature to jCarousel

JavaScript
1

I am using this carousel plugin

It is working well, but I want to add a feature where, on page load, a random image (not the first one) appears.

Here is my setup:

I am thinking I could use this method perhaps:

How could I use this? Could I initiate a movement of previous or next on page load?

Thanks so much for any insight
