You know what? The alt attribute should be more descriptive of what the image is. The title attribute is a better use for a caption in our lightbox. I've updated the index.html with placeholder text for all the alt attributes and added title attributes. Have a look for yourself in the index.html file to see the new markup. Pay close attention to where the title attributes are now. This will be the text for our caption. Alter the existing code to use the correct attribute for the caption.
//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();
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();
});

231,275 PointsAre you unsure of what the task is? The code given uses the alt attribute of the image to create the caption in the lightbox.
For this challenge, you will change the code that creates the caption so it will use the title attribute instead of the alt attribute.
Can you do it now?

231,275 PointsAs I said before, you will change the code that creates the caption so it will use the title attribute instead of the alt attribute.
If you're not sure how to do that, you might want to review the previous video and/or the JQuery API documentation for .attr().

231,275 PointsLook for where captionText is being created.

231,275 PointsSteven Parker
231,275 PointsSo your line 28 looks like this, right?
var captionText = $(this).children("img").attr("title");If it does, and you didn't change anything else, you should pass the challenge!
