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(); });

Hi Imad...like two months later.

If you're still there:

You just need to set the .attr value to title so that the caption text will appear along with the title attribute like so:

var captionText = $(this).children("img").attr("title");
  $caption.text(captionText);

Cheers:-)
