How do I get fancybox 2 to NOT loop?

Question

I'm putting together a site that involves a lightbox (fancybox 2). It works great. One change I made for the client was in the CSS so that the previous and next arrows would be "visible" all the time, rather than only when hovering over the box. Seemed to make it more intuitive.
The thing I am now wondering is HOW can I change it so that when one OPENS the fancybox there will only be a NEXT arrow until the second (and subsequent) pictures open -- AND only be a PREVIOUS arrow when one gets to the end? In other words, how do I make it not loop back to the first picture? I went in the js file and changed loop to "false", but that didn't seem to do the trick.
Anyone here familiar with how to accomplish this?
Here's a link to the site. If you click on the fourth thumbnail and click through the pictures you will see what I mean. I'd like it to be one-directional, not circular or "looping" back to the first.

Any help appreciated!

Perfect, Osgood. Thanks so much!
That's exactly what I'm looking for EXCEPT that I have previously added a "helper" to get the titles to display INSIDE the fancybox. I tried what you suggested on its own and it works exactly as I want. But how do I add it to what I already have (see script below, which includes the carouFredsel) so I can keep those captions or titles inside the box? I've tried placing it pretty much everywhere without success, but I'm sure it's just something simple that I'm not understanding.
I'm new to scripting and jQuery. When I finish this project for my client I want to dive into a book and learn jQuery. But for the time being any help would be greatly appreciated.
Also, notice my last bracket before the end script tag. Do I need that semicolon?

<script>
$(document).ready(function() {
$("#foo1").carouFredSel({
    circular: false,
    infinite: false,
    auto    : false,
    prev    : {
        button  : "#foo1_prev",
        key     : "left"
    next    : {
        button  : "#foo1_next",
        key     : "right"
    pagination  : "#foo1_pag"
$(document).ready(function(){
$(".fancybox").fancybox({
    helpers:  {
        title : {
            type : 'inside'
        overlay : {
            showEarly : false
</script>
