[jQuery] Jquery Lightbox issue in IE7

[jQuery] Jquery Lightbox issue in IE7


I have used Lightbox for portfolio, it works well in all browsers on
my locale machine. When I upload it on server for first time I can see
& click "Next" but for second image "Next" button goes down.
Please let me know if there is any solution.
