/* 
    lightbox
*/

var $overlay = $('<div id="overlay"></div>');

var $image = $('<img>');

//an aimage to overlay
$overlay.append($image);

//add overlay
$('body').append($overlay);

//Capture click event on a link to an image
$('#gallery a').click(function(event) {
    event.preventDefault();
    var imageLocation = $(this).attr('href');
    //Update overlay with th eimage linked in the link
    $image.attr("src", imageLocation);
    //Show the overlay
    $overlay.show();
});

//When overlay is clicked
$overlay.click(function() {
    //Hide the overlay
    $overlay.hide();
});`
