The animations shouldn't have anything to do with Java... animated GIFs are a "basic" internet format that any browser should display without the help of any plugins.
I think we've tried this before with no luck... but check Tools => Internet Options => "Advanced" tab => scroll down to "Multimedia" and look for "Play Animations in Web Pages".
Make sure it is "checked". If it is, try unchecking it, close and then restart the browser, then go to the same options box and recheck it.
