jQuery - how to loop through array when clicking a link?

Question

I am trying to change the src of an image when clicking on individual links (I only have 3).

So if I click on link #1, the src changes, if I click on link #2 it changes to something else, kind of like a basic image slider.

Here is a simplified example:http://jsfiddle.net/BVmUL/164/

the jquery I tried:

var images = [
    "http://lorempixel.com/400/200/",
    "http://linenwoods.com/images/kitten.png",
    "http://linenwoods.com/images/third.png"
],
    links = $("ol.list-inline > li > a"),
    img = $("figure > img");

links.each(function(){
    links.click(function(){
        img.prop("src", images[links.index()]);
        console.log($(this).index()); // only gives back 0 instead of 0,1,2 like
                                      // I expected ...
    });
});

How can I do something like this using jquery?

The anchors are inside LI elements and have no siblings, as such their index is always zero.

var images = [
    "http://lorempixel.com/400/200/",
    "http://linenwoods.com/images/kitten.png",
    "http://linenwoods.com/images/third.png"
],
    links = $("ol.list-inline > li > a"),
    img = $("figure > img");


    links.on('click', function(){
        img.prop("src", images[$(this).closest('li').index()]);
    });
});

get the index() of the parent LI instead

I forgot to ask: can I add fadeIn() or fadeOut() easily with your code to add a fade effect when the img changes?
