lightbox2

Hi,
lightbox2 doesn't work in IE7 and 8

It works perfect in FF, Opera and Safari

Drupal 6.15,image gallery 6x1.0 beta, view image.gallery, lightbox2, newest updates!

In IE7 and 8 there is shown only the first picture in original format , no thumbnails
The show doesn't start not at all

What can I do?

Sorry for my english
