Why are we using href instead of src to include the image?

var imageLocation=$(this).attr('href'); $image.attr('src',imageLocation); $overlay.show();

For this part of the code, I don't understand why we update the image src with href values? What's the difference between using src and href in this case? Why can't we either use image.attr('href') or image.attr('src') or image(imageLocation)?

If you look at the html you can see that the <a> tags have an href value that refers to an image. Images do not have href attributes. As you know, they only have src values which define the location for an image. What the code does is, it gets the href value of the clicked <a> tag and makes that href value the src of the image. Simply put, the a tag's href value just points to where a image is so when a user clicks on the link, the image that we build using jQuery has a src value. Hope this helps!
