    Marquee meet at the center

    I've 2 Marquee images one moving in from the left and the other moving in from the right.

    I like the 2 images to meet at the centre of the page. Any suggestion ?

    Thanks

    vwphillips,

    Good stuff !!!

    What if the 2 images arrived at the centre with one image on top and the other on the bottom but meet as one complete image in the centre.
    Again both images moving from 2 directions, one on top and the other bottom.
    Also they start off at higher speed but slowing down as they meet in the centre.

    Many Thanks

    vwphillips,

    You're a champion!!

    The only problem I have is my 2 images size are

    top.jpg 600x282
    bottom.jpg 600x312

    When I replaced these 2 images into your code, it overlapped at the centre.

    Thanks again!!
