Jquery.Animate animation not smooth?

Question

JavaScript

There is a page with many pictures on it, it is large - 4000x2000. And in some browsers, animation made through jquery.easing.1.3 (and without it, too, no difference)

$("html:not(:animated)"+( ! $.browser.opera ? ",body:not(:animated)" : "")).animate({scrollTop: temptop+'px',scrollLeft: templeft+'px'}, {duration: 3000, easing: "easeInOutExpo"});

slows down.
Example: vintage.skulditsky.kz/index.html JQuery
experts, please help!
