Old path reference in prev/next gifs for lightbox

I moved my WP to a new host address and gif’s for Next / Prev / Close still reference to old path when I use Lightbox. You can check it here.

Not sure if it’s important but before switching I replace gif’s graphics. Before it was text ‘Next’ etc now just graphic with arrow but the names of gif’s stayed the same.

I’ve downloaded all files of my wordpress and database and searched for text string with my old domain but no results.
I also did everything what said in this post: http://www.nextgen-gallery.com/galleries-opening-lightbox/

Please help: I’ve spent 2 days for that and still can’t figure it out guys.
