Why wouldn't you assign the caption text before showing the overlay?

Wouldn't it be better to add the caption text to the paragraph before showing the overlay like so...

$("#imageGallery a").click(function(event){
  event.preventDefault();
  var imageLocation = $(this).attr("href");
  $image.attr("src", imageLocation);
  var captionText = $(this).children("img").attr("alt");
  $caption.text(captionText);
  $overlay.show();


});

That's not a bad idea.

But in practice, both operations will happen so quickly that the user is not likely to see a difference.

Yet my inclination would be to do it just as you are suggesting.
