    Thank you very much for code and could you help me with one more thing.

    That script works perfectly fine and thanks a lot for that. One more thing please, when I put two scripts in one page (horizontal and vertical scrolling) neither of them works. But when I have only one of them it works perfectly. Would it be possible to get both up/down and left/right in one script? Like this http://myimages.bravenet.com/379/358...screenshot.jpg
    If possible could you arrange like that please because with one script it stays at the bottom right corner no matter how much I resize the window.
