    <div class="abigimage-wrapper">
        <div class="abigimage-box">
            <!-- prevBtnBox - clickable behind the image, width 50% -->
            <div class="abigimage-prevBtnBox"></div>
            <!-- closeBtnBox - clickable behind the image, width 50% -->
            <div class="abigimage-closeBtnBox"></div>
            <img class="abigimage-img">
            <img class="abigimage-imgNext">
            <img class="abigimage-imgPrev">
        </div>
    </div>
    <div class="abigimage-top">
        <div class="abigimage-prevBtn"><!-- prevBtnHtml --></div>
        <div class="abigimage-nextBtn"><!-- nextBtnHtml --></div>
        <div class="abigimage-counter"></div>
        <div class="abigimage-closeBtn"><!-- closeBtnHtml --></div>
        <div class="abigimage-zoomOutBtn"><!-- zoomOutBtnHtml --></div>
        <div class="abigimage-zoomInBtn"><!-- zoomInBtnHtml --></div>
    </div>
    <div class="abigimage-bottomBox">
        <div class="abigimage-bottom"></div>
    </div>
</div>

Using onopen handler

Function, defined as onopen handler, executes in context of plugin, and receives target element as argument. Plugin elements available in this context as properties.

$('a[href$=".jpg"]').abigimage({
    onopen: function (target) {
        this.bottom.html(
            /* bottom caption */
            $('img', target).attr('alt') +
            /* custom bottom area */
            ($('span', target).html() || '')
        );
    }
});

Using custom links with data-href attribute

If you want different link for plugin's big image and for non-javascript clients (search engines or browsers without javascript) - use data-href attribute:

<a href="/non_javascript_link.html" data-href="/images/big/myimage.jpg"> ... </a>

Also, you can use data-href attribute on any element, not only links.

Static methods

• open([src], [index], [sel]) - open image by URL or index.
• next([sel]) - open next image.
• prev([sel]) - open previous image.
• close([sel]) - close image.
• unbind([sel]) - unbind plugin events.

/* open image by URL */
$.abigimage.open('/awesomeimage.jpg');

/* open image by index */
$.abigimage.open(2);

/* open image by URL at specified position */
$.abigimage.open('/awesomeimage.jpg', 5);

/* open next image */
$.abigimage.next();

/* open previous image */
$.abigimage.prev();

/* close image */
$.abigimage.close();

/* unbind plugin events */
$.abigimage.unbind();

All static methods by default tries to execute on current opened plugin insatnce, if no instances opened, tries to execute on last created instance. You can specify instance by passing it's selector in last argument sel.

$myimgs1 = $('.myimgs1 a').abigimage();
$myimgs2 = $('.myimgs2 a').abigimage();

$.abigimage.open('/awesomeimage.jpg', null, $myimgs2);
$.abigimage.unbind($myimgs1);
