Slideshow on ASP.NET Website Problem

I am attempting to run a slideshow of images.
I have the correct call from the website and as far as I can tell the paths are correct.
But it is giving a blank image.
Here is where I think it is going wrong.

function initSlideShow() {
    document.getElementById('arrow_left').onmousemove = startSlide;
    document.getElementById('arrow_left').onmouseout = releaseSlide;
    document.getElementById('arrow_right').onmousemove = startSlide;
    document.getElementById('arrow_right').onmouseout = releaseSlide;
    imageGalleryObj = document.getElementById('theImages');
    imageGalleryLeftPos = imageGalleryObj.offsetLeft;
    imageGalleryWidth = document.getElementById('galleryContainer').offsetWidth - 80;
    maxGalleryXPos = imageGalleryObj.offsetLeft;
    minGalleryXPos = imageGalleryWidth - document.getElementById('slideEnd').offsetLeft;
    var slideshowImages = imageGalleryObj.getElementsByTagName('IMG')
    for (var no = 0; no < slideshowImages.length; no++) {
        slideshowImages[no].onmouseover = showImage;
    }
    var divs = imageGalleryObj.getElementsByTagName('DIV');
    for (var no = 0; no < divs.length; no++) {
        if (divs[no].className == 'imageCaption') imageGalleryCaptions[imageGalleryCaptions.length] = divs[no].innerHTML;
    }
    gallerySlide();
}

I cannot see where I am falling off the log on this.

Any help?


I hope the question is clear and trust that there are sage developers who can cast a caustic eye over my problem.
