Line 19 shows where I am preventing the browser from going to the next page. It works as it is supposed to. It doesn't make sense that treehouse is saying I'm wrong.
//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>");
var $caption = $("<p></p>");
//An image to overlay
$overlay.append($image);
//A caption to overlay
$overlay.append($caption);
//Add overlay
$("body").append($overlay);
//Capture the click event on a link to an image
$("#imageGallery a").click(function(event){
event.preventDefault(event);
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 title attribute and set caption
var captionText = $(this).children("img").attr("alt");
$caption.text(captionText);
});
//When overlay is clicked
$overlay.click(function(){
//Hide the overlay
$overlay.hide();
});

you need to call the preventDefault function on the event object. You don't need to pass it anything.
