I have hand-built a dropdown menu and my client wants me to replace the picture with an animation (just a few pictures fading in and out). When I do this the dropdown menu no longer appears. Am I doing something wrong?

Here is the page without the animation (and the drop-down works):

Here is the page with the animation:

Thanks!
