Should show up as a lightbox but instead just shows normal in the left in te screen

//Problem: User when clicking on image goes to a dead end
//Solution: Create an overlay with the large image - Lightbox

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

$overlay.append($image);

//Add overlay
$("body").append($overlay);
  //An image
  //A caption


//Capture the click event on a link to an image
$("#imageGallery a").click(function(event) {
  event.preventDefault();
  var imageLocation = $(this).attr("href");

  //update overlay with the image linked in the link
  $image.attr("src", imageLocation);

  //Show the overlay
  $overlay.show();



  //Get Child's alt atribute and set caption

});


// When overlay is clicked
  //Hide the overlay

Can somebody see what the problem is? The image needs to show up as a lightbox.

Samy, did you add the necessary styles (on the style sheet) to the #overlay selector and the #overlay img selector? The style you need on #overlay will center the image horizontally and the style for #overlay img will give a 10% top margin to the image on the overlay.
