jQuery Carousel (CarouFredSel) stop animation if only 3 images

Question

OK, slightly complex question. I have a carousel on my page (using CarouFredSel plugin) sometimes this carousel will have 3 images in it, sometimes 4 or more. The carousel is set to display 3 images at a time, with the center image being larger.

My issue is this, if I only have 3 images, I can't slide the carousel left and right in order to make the adjacent images central (and therefore larger). To get around this I add a dummy image (i.e. just write <img src="" /> so the slider thinks there are 4 images, this allows me to slide, however, I want to be able to stop the slider before getting to the 4th 'dummy' image.

My HTML is as follows:

<div id="wrapper">
        <div id="carousel">
            <img src="http://www.samskirrow.com/client-kateguest/wp-content/uploads/2013/09/Christmas.jpg" />
            <img src="http://www.samskirrow.com/client-kateguest/wp-content/uploads/2013/09/Birds.jpg" />
            <img src="http://www.samskirrow.com/client-kateguest/wp-content/uploads/2013/09/christmas_alt2.jpg" />
            <img src="" />

        </div>
            <a id="prev2" class="prev" href="#">&lt;</a>
            <a id="next2" class="next" href="#">&gt;</a>
    </div>

and jQuery for the slider plugin:

$(function() {

            var _center = {
                width: 275,
                height: 390,
                marginLeft: 0,
                marginTop: 0,
                marginRight: 0
            };
            var _left = {
                width: 140,
                height: 200,
                marginLeft: 0,
                marginTop: 100,
                marginRight: 20
            };
            var _right = {
                width: 140,
                height: 200,
                marginLeft: 20,
                marginTop: 100,
                marginRight: 0
            };
            var _outLeft = {
                width: 100,
                height: 100,
                marginLeft: 150,
                marginTop: 200,
                marginRight: -150
            };
            var _outRight = {
                width: 100,
                height: 100,
                marginLeft: 0,
                marginTop: 200,
                marginRight: 0
            };
            $('#carousel').carouFredSel({
                auto: false,
                prev: {
                    button: "#prev2",
                    key: "left"
                },
                swipe: true,
                width: 597, 
                height: 392,
                align: false,
                items: {
                    visible: 3,
                    width: 100
                },

                next: {

                        data.items.visible.eq( 0 ).animate(_left).removeClass('center right').addClass('left');
                        data.items.visible.eq( 1 ).animate(_center).addClass('center').removeClass('right left');
                        data.items.visible.eq( 2 ).animate(_right).css({ zIndex: 1 }).removeClass('left center').addClass('right');
                        data.items.visible.eq( 2 ).next().css(_outRight).css({ zIndex: 0 });

                        setTimeout(function() {
                            data.items.old.eq( 0 ).css({ zIndex: 1 });

                            data.items.visible.eq( 2 ).css({ zIndex: 2 });
                        }, 200);
                    }
                },
                prev: {

        });

Answer 1

you need to add the minimum to your code:

"Minimum: Number The minimum number of items needed to create a carousel. If null, the number for items.visible is inherited and increased by 1." ( from their website)

adding that tag to your code this one will look like:

            items: {
                visible: 3,
                minimum: 3,
                width: 100
            },

instead of:

            items: {
                visible: 3,
                width: 100
            },
