I am trying to create a like/unlike button for my website.

If you visit  http://callummundine.com.au/photo/explore_photos.php and hover over the first photo, you can click the like button. As you can see, i have managed to get it to switch between 'Like' and 'Unlike', but it removes the icon.

Any ideas?

Here is the code:

2. <script>
3. $("#like-unlike").click(function(e) {
4. if ($(this).html() == "Like") {
5. $(this).html('Unlike');
6. }
7. else {
8. $(this).html('Like');
9. }
10. return false;
11. });
12. </script>
