If a user clicks in the reply button of a comment, it is shown the image
ajax-loader.gif. This is ok.

The problem is: sometimes nothing happens (probably because of slow internet
connection) and then a user clicks the button again. In this case, the image is
added two times. If the user clicks again and again, it will be added new
copies of that image for each click. This should be avoided.

Notice that if more than one image was shown, when the script finishes loading
the box for new comments, only the first image will be removed, causing the
impression that there still have something to wait...
