JQuery :: Rotate Through Images Automatically When Icon Clicked

I wrote a little jquery that will rotate through images automatically and when you click on an it's icon. If I let the rotator cycle throught the images everything is fine, but when I click on it's icon, the div tag that holds the images gets space added to the bottom and I can't figure out why? I tried everything css related so this appears to be something jquery related.

Here is the code that is used for flipping through the images:
$("#button2").click(function(){
$("#block-block-4").fadeIn("fast");
$("#block-block-3, #block-block-6, #block-block-7, #block-block-8").hide(); });
